„Color Memory“ mit Arduino: Programmieren und Spaß haben
Auf Instagram bin ich auf das interessante Projekt „Color Memory“ von Sunflower gestoßen. Dieses kleine Spiel überzeugt durch seinen einfachen Aufbau und eignet sich hervorragend für Einsteiger, die grundlegende Programmierkonzepte und den Umgang mit dem Arduino kennenlernen möchten. Es bietet eine praktische Möglichkeit, Abläufe im Code zu verstehen und eine Schaltung mit LEDs und einem Piezo-Buzzer zu erstellen. Dabei lernst du, wie du if-Bedingungen verwendest, Arrays einsetzt und die Steuerung von Hardwarekomponenten wie LEDs und Buzzern programmierst. Zusätzlich ermöglicht das Projekt, erste Erfahrungen in der Strukturierung und Erweiterung von Code zu sammeln – perfekt, um die Grundlagen der Mikrocontroller-Programmierung zu vertiefen. https://youtu.be/SV_pxPFMMFA Disclaimer: Die Idee für das Projekt „Color Memory“ stammt vom Instagram-Account Sunflower. Ich habe mich von diesem Beitrag inspirieren lassen und das Spiel für meinen Technikblog aufgegriffen. Die Umsetzung und Beschreibung basieren auf meinen eigenen Anpassungen und Interpretationen des ursprünglichen Konzepts. Ein herzliches Dankeschön an Sunflower für die kreative Idee und die Inspiration!
Ablauf des Spieles - Color Memory
Das Spiel beginnt mit dem zufälligen Aufleuchten einer Sequenz von LEDs, die vom Mikrocontroller vorgegeben wird. Sobald die Sequenz beendet ist, ertönt ein Signalton vom Piezo-Buzzer, der den Spieler auffordert, die Reihenfolge der LEDs korrekt nachzubilden. Der Spieler gibt die Sequenz ein, indem er beispielsweise Tasten drückt, die den jeweiligen LEDs zugeordnet sind. Wird die Reihenfolge korrekt wiederholt, erhält der Spieler einen Punkt, und die Sequenz wird in der nächsten Runde um eine LED erweitert. Mit jedem Level steigt die Schwierigkeit, da die Reihenfolge länger und komplexer wird. Ein Fehler in der Eingabe beendet das Spiel. Ziel ist es, so viele Runden wie möglich zu meistern!
Was lernt man bei der Programmierung?
Du lernst, wie du Zufallszahlen erzeugst, um die Reihenfolge der LEDs zu bestimmen, Arrays anlegst und dynamisch befüllst, um die Sequenz zu speichern, sowie digitale Pins programmierst, um LEDs und einen Piezo-Buzzer anzusteuern. Dieses Projekt kombiniert spielerischen Spaß mit praktischen Lernerfahrungen in der Mikrocontroller-Programmierung und eignet sich hervorragend, um deine Fähigkeiten gezielt auszubauen.
Was wird für den Aufbau der Schaltung benötigt?
In meinem Fall verwende ich für die Schaltung: - einen Arduino UNO R3*, oder - einen Arduino Nano V3 - vier, 5 mm LEDs* inkl. 220 Ohm Vorwiderstand* - vier Taster mit farbigen Tastknöpfen* - eine I2C, 4fach 14 Segmentanzeige* - diverse Breadboardkabel* - ein 830 Pin Breadboard*
Statt einem Arduino UNO R3 kannst du ebenso ein Arduino Nano oder ESP32 verwenden. Der UNO R3 hat sich in diesen Schaltungen etabliert, da dieser bei diversen Kits enthalten ist. Hinweis von mir: Die mit einem Sternchen (*) markierten Links sind Affiliate-Links. Wenn du über diese Links einkaufst, erhalte ich eine kleine Provision, die dazu beiträgt, diesen Blog zu unterstützen. Der Preis für dich bleibt dabei unverändert. Vielen Dank für deine Unterstützung!
Aufbau der Schaltung
Wie erwähnt kannst du die Schaltung am Arduino UNO und Nano aufbauen (selbstverständlich auch am Leonardo sowie Mega 2560 R3).
Schaltung - Color Memory am Arduino UNO R3
Programmieren des Spieles - Color Memory in der Arduino IDE
Wie eingangs erwähnt, bietet dir die Programmierung dieses Spiels eine wertvolle Grundlage für viele weitere Spiele und Projekte. Im Laufe der Entwicklung wirst du wichtige Techniken und Konzepte kennenlernen, die dir auch bei zukünftigen Vorhaben nützlich sein werden. In den folgenden Abschnitten zeige ich dir Schritt für Schritt, wie du dieses kleine, aber spannende Spiel selbst programmieren kannst. Schritt 1 - Abfragen von Taster & aufleuchten von LEDs Im ersten Schritt fragen wir die Taster ab und lassen die LEDs aufleuchten. Die Taster müssen entprellt werden, dazu kannst du entweder nach jedem Tastendruck eine Zeit x warten (Funktion delay) oder du nutzt die Bibliothek Bounce2. Der Weg über die Bibliothek ist deutlich komfortabler, da du hier zusätzlich abfragen kannst, ob der Taster gedrückt gehalten wird oder losgelassen wurde. #include #define tasterBlauPin 3 #define tasterGruenPin 5 #define tasterGelbPin 7 #define tasterRotPin 9 Bounce tasterBlau = Bounce(); Bounce tasterGruen = Bounce(); Bounce tasterGelb = Bounce(); Bounce tasterRot = Bounce(); const int BOUNCE_INTERVAL = 5; void setup() { Serial.begin(9600); tasterBlau.attach(tasterBlauPin, INPUT_PULLUP); tasterBlau.interval(BOUNCE_INTERVAL); tasterGruen.attach(tasterGruenPin, INPUT_PULLUP); tasterGruen.interval(BOUNCE_INTERVAL); tasterGelb.attach(tasterGelbPin, INPUT_PULLUP); tasterGelb.interval(BOUNCE_INTERVAL); tasterRot.attach(tasterRotPin, INPUT_PULLUP); tasterRot.interval(BOUNCE_INTERVAL); } void loop() { tasterBlau.update(); tasterGruen.update(); tasterGelb.update(); tasterRot.update(); if (tasterBlau.rose()) { Serial.println("Taster BLAU betätigt!"); } if (tasterGruen.rose()) { Serial.println("Taster GRUEN betätigt!"); } if (tasterGelb.rose()) { Serial.println("Taster GELB betätigt!"); } if (tasterRot.rose()) { Serial.println("Taster ROT betätigt!"); } } Auf der seriellen Schnittstelle wird beim betätigen eines der Taster jeweils der entsprechende Text "Taster betätigt!" ausgegeben.
Die LEDs sollen jeweils nur kurz aufleuchten, dazu erstellen wir eine Funktion, welcher wir den Pin der LED übergeben und dort einfach diese aktiviert, eine Pause eingelegt und anschließend deaktiviert wird. #include #define ledBlau 2 #define ledGruen 4 #define ledGelb 6 #define ledRot 8 void setup() { Serial.begin(9600); pinMode(ledBlau, OUTPUT); pinMode(ledGruen, OUTPUT); pinMode(ledGelb, OUTPUT); pinMode(ledRot, OUTPUT); } void blinkLed(int ledPin) { digitalWrite(ledPin, HIGH); delay(500); digitalWrite(ledPin, LOW); } void loop() { blinkLed(ledBlau); blinkLed(ledGruen); blinkLed(ledGelb); blinkLed(ledRot); } Schritt 2 - Erzeugen von Zufallszahlen Die Erzeugung echter Zufallszahlen ist für Computer eine komplexe Aufgabe, da sie dazu neigen, wiederkehrende Muster zu erzeugen oder Werte auf Basis mathematischer Funktionen zu berechnen. Diese Werte sind somit oft vorhersagbar und nicht wirklich zufällig. Mikrocontroller wie der Arduino bieten jedoch eine clevere Lösung für dieses Problem: Durch das Abgreifen eines Startwertes (Seed) von einem ungenutzten analogen Pin – zum Beispiel A0 – können wir eine unvorhersehbare Datenquelle nutzen. Der analoge Pin liefert durch elektrische Rauscheffekte stets leicht variierende Werte, die wir als Grundlage für echte Zufallszahlen in einer definierten Range (Bereich) verwenden können. Auf diese Weise wird das Verhalten des Spiels jedes Mal einzigartig und authentisch zufällig. Da wir in diesem Spiel lediglich eine Range von 0 bis 4 verwenden (entsprechend der Farben Blau, Grün, Gelb und Rot), besteht die Möglichkeit, dass eine Zahl mehrfach hintereinander generiert wird. Um dies zu verhindern, habe ich die Funktion generateUniqueRandomNumber erstellt. Diese überprüft, ob die neu generierte Zahl bereits zuvor verwendet wurde. Falls dies der Fall ist, ruft sich die Funktion selbst erneut auf, bis eine eindeutige, noch nicht genutzte Zahl gefunden wird. So bleibt die Sequenz abwechslungsreich und die Herausforderung für den Spieler erhalten. int lastRandomNumber = -1; void setup() { Serial.begin(9600); randomSeed(analogRead(0)); } int generateUniqueRandomNumber() { int randNumber = random(0, 4); if (randNumber != lastRandomNumber) { lastRandomNumber = randNumber; return randNumber; } return generateUniqueRandomNumber(); } void loop() { Serial.println(generateUniqueRandomNumber()); delay(500); } Die ermittelten Zufallszahlen werden in diesem kleinen Sketch im seriellen Monitor der Arduino IDE ausgegeben.
Schritt 3 - Abspeichern von Zufallszahlen in Arrays In Arrays kannst du gleichartige Daten speichern, die Größe des Arrays ist am Mikrocontroller nur durch den vorhandenen Speicher begrenzt. In meinem Fall lege ich eine größe von 10 fest. Damit kann der Spieler bist maximal Level 10 spielen. Derzeit belegt das gesamte Spiel auf einem Arduino UNO R3 31% des Speicherplatzes für Globale Variablen du kannst also diesen Wert von 10 auf 60 erhöhen! (Angenommen der Benutzer schafft es dann auch 60 folgen von LEDs sich zu merken :) ) Der Sketch verwendet 9382 Bytes (29%) des Programmspeicherplatzes. Das Maximum sind 32256 Bytes. Globale Variablen verwenden 640 Bytes (31%) des dynamischen Speichers, 1408 Bytes für lokale Variablen verbleiben. Das Maximum sind 2048 Bytes. Das derzeitige Level wird über eine 4fach 14 Segmentanzeige visualisiert. Für diese Anzeige verwende ich die Bibliothek Adafruit LED Backpack welche ich bereits im Beitrag Arduino Lektion #108: 14 Segmentanzeige verwendet habe. #include #include "Adafruit_LEDBackpack.h" #define ledBlau 2 #define ledGruen 4 #define ledGelb 6 #define ledRot 8 int lastRandomNumber = -1; int leds = { ledBlau, ledGruen, ledGelb, ledRot }; int level = 1; int sequenz = {}; Adafruit_AlphaNum4 alpha4 = Adafruit_AlphaNum4(); void setup() { Serial.begin(9600); randomSeed(analogRead(0)); pinMode(ledBlau, OUTPUT); pinMode(ledGruen, OUTPUT); pinMode(ledGelb, OUTPUT); pinMode(ledRot, OUTPUT); alpha4.begin(0x70); alpha4.setBrightness(15); } void generateSequenz() { Serial.println("generateSequenz"); for (int index = 0; index sequenz = leds; } } void playSequenz() { Serial.println("playSequenz"); for (int index = 0; index int ledPin = sequenz; blinkLed(ledPin); } } void blinkLed(int ledPin) { digitalWrite(ledPin, HIGH); delay(150); digitalWrite(ledPin, LOW); } int generateUniqueRandomNumber() { int randNumber = random(0, 4); if (randNumber != lastRandomNumber) { lastRandomNumber = randNumber; return randNumber; } return generateUniqueRandomNumber(); } void displayLevel() { String msg = (level alpha4.writeDigitAscii(0, msg.charAt(0)); alpha4.writeDigitAscii(1, msg.charAt(1)); alpha4.writeDigitAscii(2, msg.charAt(2)); alpha4.writeDigitAscii(3, msg.charAt(3)); alpha4.writeDisplay(); } void loop() { displayLevel(); generateSequenz(); playSequenz(); delay(150); level++; if (level > 10) { level = 1; } } Schritt 4 - Erzeugen von Tönen mit einem Piezo Buzzer Über den Piezo Buzzer kannst du nicht nur einfache Töne sondern auch kleine Lieder abspielen (siehe Weihnachtsevent 2019 im JFZ Schöningen – “Löten eines Weihnachtsbaums mit Sound”). In diesem Spiel nutzen wir diesen als Startsignal für den Spieler damit dieser die zuvor abgespielte Sequenz wiederholt. #define piezoBuzzerPin 13 void setup() { pinMode(piezoBuzzerPin, OUTPUT); } void loop() { tone(piezoBuzzerPin, 1400, 75); delay(500); tone(piezoBuzzerPin, 500, 75); delay(500); } Das kleine Beispiel spielt auf dem Piezo Buzzer zwei Töne ab, einer mit der Frequenz von 1400 Herz und ein anderer mit 500 Herz. (Je höher die Herz desto höher ist der Ton.) Zwischen diesen beiden Tönen wird eine Pause von 500 Millisekunden eingelegt.

The TinkerKit Inputs allow for easy connection between the sensor modules and 3-pin connectors.
The TinkerKit Outputs allow for easy connection of the TinkerKit actuator modules via the 3-pin connectors.
The TFT display connector can be used for a color LCD screen, SD card, or any other devices utilizing the SPI protocol.
To fully utilize all available sensors, the board employs an analog multiplexer. This way, multiple input channels (excluding the 3-axis accelerometer) can share a single analog input of the microcontroller. Selecting which channel to read is done through four additional pins on the microcontroller.
Communication is essential in any relationship, whether it be personal or professional. It plays a crucial role in maintaining strong connections and fostering understanding between individuals. Effective communication allows for open and honest dialogue, facilitating problem-solving and building trust. Without good communication, misunderstandings can occur, leading to conflicts and strained relationships. Therefore, it is important to prioritize effective communication in every aspect of our lives.
The ESPLORA Arduino game controller Board for the Leonardo offers various features for connecting with a computer, another Arduino, or different micro-controllers. The ATmega32U4 enables serial (CDC) communication through USB and is recognized as a virtual com port on the computer. It also functions as a full speed USB 2.0 device and can be used with standard USB COM drivers. A .inf file is needed for Windows.
The Arduino software comes equipped with a serial monitor for easy transmission of text data to and from the board. Whenever data is being sent via the USB connection to the computer, the RX and TX LEDs will light up on the board. Additionally, the ATmega32U4 has SPI capability accessible through the SPI library. In addition, the Esplora can act as a standard keyboard and mouse, allowing you to use programming to manage these input devices via the Keyboard and Mouse libraries.
The act of creating computer software, also known as programming, involves writing code using various languages and tools. This process requires a combination of problem-solving skills, critical thinking and creativity. Programmers must constantly learn new techniques and adapt to ever-changing technology in order to produce high-quality programs.
To start using the Esplora with your Arduino software (download), simply choose “Esplora” from the Tools > Board menu. For more information, refer to the getting started page. The ATmega32U4 on the Esplora comes pre-loaded with a boot-loader, enabling you to upload new code without an external hardware programmer.
The AVR109 protocol is the chosen method of communication. To avoid using the bootloader, you can program the microcontroller through the ICSP header. Additional instructions are available for reference.
A dedicated library for the Esplora simplifies writing sketches, with methods available for reading sensors and controlling onboard outputs. These high-level methods also perform pre-processing of data, such as converting temperature readings to degrees Fahrenheit or Celsius. Additionally, the library allows easy access to outputs like the RGB LED. For further information and examples, please refer to the Esplora library reference page.
The automatic reset and bootloader activation are key components in the software’s functioning.
Rather than relying on the physical reset button, the Esplora utilizes a software-based reset triggered by opening and then closing the virtual serial/COM port (CDC) at 1200 baud. This initiates a processor reset, temporarily cutting off the USB connection to the computer and causing the virtual port to disappear. The boot-loader remains active for approximately 8 seconds before it can also be activated by pressing the reset button on the Esplora.
Please be aware that upon initial power up, the board will launch the user sketch instead of the boot-loader, if available. Due to the specific reset process of the Esplora, it is most effective to allow the Arduino software to attempt a reset before uploading, especially if you typically press the reset button before uploading on other boards. However, in the event that the software is unable to reset the board, you can manually initiate the boot-loader by pressing the reset button on the board.
The USB port is equipped with overcurrent protection to prevent any potential damage.
The ESPLORA Arduino game controller Board comes equipped with a re-settable poly-fuse to safeguard your computer’s USB ports against shorts and over-current. While most computers have built-in protection, the fuse adds an additional level of security. In the case of a short or overload exceeding 500 mA, the fuse will disconnect the connection until the issue is resolved.
Regarding the appearance of this object, its external features will be discussed.
The ESPLORA Arduino game controller Board PCB has a maximum size of 6.5 inches in length and 2.4 inches in width. The USB and TinkerKit connectors extend beyond the width dimension. Additionally, there are four screw holes that allow for attachment to a surface or case.

This week I experimented with amplifying signals using transistors. Unfortunately, I didn’t buy an Arduino Leonardo yet, which is why the Keypress library did not work. As an alternative, I used Serial Communication (p5.serialcontrol) to connect the Arduino to my game.

I ended up gutting mine and putting an Arduino due or Leonardo in there (one that can handle mouse and keyboard output, can't remember which board exactly) and got it to work the way I wanted. The board itself didn't even fit so it became a weird Frankenstein of nodes connected together.
It uses a membrane keyboard that I ended up manually mapping to hard coded macros on the Arduino, and the keyboard quality honestly is kind of trash, it's just a really cool form factor.
It was tricky as hell to figure out the mapping on the joystick because despite having an x and y axis, I think it was rotated at a weird angle to fit in the case? It's been years so I can't recall exactly how I handled it, but the long and short of it is that I dropped the proprietary software because it was too limiting.
I'll post pictures later if I can find it.
no idea if this is the format for this, I'm new here I swear I'm not a bot, I feel like you posted a while ago about using a Logitech G13 as a hip mounted keyboard. If that's not right I'll fuck right off but if you did did you get the joystick to work? If so: how? I got one independent of seeing that and I'm trying to get games to recognize that the joystick and joystick and it's driving me up a wall
It wasn't a G13, it was a Belkin N52 Nostromo because its primary construction features a gap for a belt-loop.
Can you send me a photograph of the serial number of your device, or tell me which version of the G13 you have, and we'll troubleshoot it?
I've been thinking of buying a G13 to take it apart and study it so I'm going to look at this as a learning experience.

LCD Keypad Shield für Arduino: Einsteigerfreundliches Display mit Tastensteuerung
Das coole LCD Keypad Shield gibt es schon sehr lange auf dem Markt und wurde auch auf anderen Seiten schon beschrieben. Dieser Beitrag soll jedoch etwas tiefer gehen und ich möchte dir, nachdem ich den Aufbau und die Programmierung erläutert habe, ein cooles nützliches Projekt mit diesem zeigen. https://youtu.be/4eqaoDKCIZU Ich möchte meinem ehemaligen Abteilungsleiter im Elektroniklabor herzlich danken. Durch die großzügige Möglichkeit, sich bei der Auflösung des Labors zu bedienen, konnte ich unter anderem das LCD Keypad Shield für Arduino erhalten.
Technische Daten
Zunächst zu den technischen Daten des LCD Keypad Shield: HerstellerDF-RobotBetriebsspannung5VAbmessungen80 mm x 58 mmFeatures2x16 Zeilen LCD-Display, 1x Potentiometer zur Regulierung der Hintergrundbeleuchtung, 6 Taster (davon 1 Taster für RESET),
Aufbau des LCD Keypad Shield
Das Shield verfügt über ein 2x16 Zeichen LCD-Display und sechs Tasten, welche mit SELECT, LEFT, UP, DOWN, RIGHT und RST (Reset) beschriftet sind. Zusätzlich hast du ein Drehpotentiometer zum Regulieren der Hintergrundbeleuchtung.
Aufbau des LCD Keypad Shield von DF Robot Das Shield ist fertig aufgebaut auf einer Platine, welche du direkt auf einen Arduino UNO R3 / R4, Leonardo oder Mega 2560 R3 stecken kannst. Du kannst mit zusätzlichen Stiftleisten noch die freien Pins des Mikrocontrollers nach oben führen und so an diese Pins weitere Komponenten (Sensoren, Aktoren) anschließen.
Der Mega 2560 R3 hat deutlich mehr digitale & analoge Pins und somit verbleiben noch weitere für ein eventuelles Projekt mit dem LCD Keypad Shield.
Pinout des LCD Keypad Shield
Bevor wir dieses Shield programmieren können, müssen wir zunächst prüfen, an welche Pins die Taster und das LCD-Display angeschlossen ist. KomponenteArduino UNO R3LCD-DisplayRSD8EnableD9D4D4D5D5D6D6D7D7TasterA0 Analoge Werte der Tasten am LCD Keypad Shield Die Taster sind alle am analogen Pin A0 angeschlossen und liefern beim Betätigen jeweils unterschiedliche Werte. Über diese Werte kann man die betätigte Taste im Code quasi recht einfach erkennen. Tasteranaloger WertSELECT640LEFT409RIGHT0UP99DOWN256 Unterschiede bei Mikrocontrollern Für die Schaltung in diesem Beitrag verwende ich den originalen Arduino UNO R3, dieser ist deutlich wertiger aufgebaut als die einfachen China Klone. Durch die andere Verarbeitung sind auch die Werte, welche die Tasten beim Betätigen liefern etwas anders als wie bei besagten Mikrocontrollern auch China. Getestet habe ich die Werte mit: - dem originalem Arduino UNO R3, - dem Funduino UNO R3, - einem Noname China Klone, - dem Funduino Mega 2560 R3,
Programmieren des LCD Keypad Shield in der Arduino IDE
Die Programmierung erfolgt in der Arduino IDE wobei ich hier die aktuelle Version 2.0.x verwende. Du kannst die nachfolgenden Programme aber auch in der klassischen Version 1.8.x programmieren (welche unter Umständen etwas schneller ist). Schritt 1 - auslesen der Taster Mit nachfolgendem Code lesen wir zunächst die Werte der Tasten aus und geben diese auf der seriellen Schnittstelle aus. #define taster A0 void setup() { Serial.begin(9600); pinMode(taster, INPUT); } void loop() { Serial.println(analogRead(taster)); delay(250); } Das Shield habe ich hier an einen Funduino Mega 2560 angeschlossen und dieser liefert ein paar unterschiedliche Werte für die Tasten (um genau zu sagen, um eins versetzt).
analoge Werte der Tasten am LCD Keyad Shield
Schritt 2 - Programmieren des 2x16 LCD-Display
Wie du ein LCD-Display programmierst, habe ich dir bereits im Beitrag Arduino Lektion 7: LCD Display ansteuern erläutert, hier greife ich zunächst das Beispiel auf und zeige den Text "Hallo Welt!" auf der ersten Zeile und auf der zweiten Zeile die Buchstaben A bis P. #include //Das Display ist wiefolgt mit dem Shield / Mikrocontroller verbunden /** * rs > D8 * enabled > D9 * D4 > D4 * D5 > D5 * D6 > D6 * D7 > D7 **/ LiquidCrystal lcd(8, 9, 4, 5, 6, 7); void setup() { //Das LCD-Display mit 16 Zeichen und 2 Zeilen initialisieren //Die Bibliothek LiquidCrystal kann für viele LCD-Displays verwendet werden! lcd.begin(16, 2); //Erste Zeile mit dem Text "Hallo Welt!" belegen. lcd.print("Hallo Welt!"); //Die zweite Zeile soll mit den Buchstaben A bis P belegt werden. //Dafür legen wir uns eine Variable zeichen an und weisen dieser den Wert //65 zu dieser repräsentiert den ASCII Wert A siehe (https://draeger-it.blog/ascii-tabelle/) int zeichen = 65; for (int i = 0; i < 16; i++) { //Cursor an die Position i (aus der Schleife) und Zeile 1 setzen //die erste Zeile hat den Wert 0 und die zweite 1 lcd.setCursor(i, 1); //die Zahl in ein Charakter umwandeln lcd.print(char(zeichen)); //Die Zahl um eins erhöhen. zeichen++; //eine kleine Pause von 350ms delay(350); } } void loop() { //bleibt leer } Der obige Quellcode erzeugt die Ausgabe von "Hallo Welt!" in der ersten Zeile und die Buchstabenfolge von A bis P in der zweiten Zeile.
Beispiele für das LCD Keypad Shield am Arduino UNO R3
Nachdem ich dir jetzt gezeigt habe wie dieses Shield programmiert wird, möchte ich dir nun ein paar Beispiele aufzeigen welche du damit nachprogrammieren kannst. Beispiel 1- navigieren durch ein Array Mit den Navigationstasten kannst du recht einfach über ein Array navigieren und mit der Taste SELECT die Auswahl bestätigen. Im ersten Beispiel möchte ich dir gerne zeigen wie du durch die Werte eines Arrays navigieren kannst. #include //initialisieren des Displays LiquidCrystal lcd(8, 9, 4, 5, 6, 7); //die Taster sind gemeinsam über den //analogen Pin A0 angeschlossen #define taster A0 //analoge Werte der Taster const int SELECT = 640; const int LEFT = 409; const int RIGHT = 0; const int UP = 99; const int DOWN = 256; //Aufbau des Menüs //maximale Anzahl der Einträge im Array const int NUM_MENU_ITEMS = 4; //aktueller Index int index = -1; //das Menü String menu = { "Eintrag 1", "Eintrag 2", "Eintrag 3", "Eintrag 4" }; //Feld für den Wert des Tasters welcher betätigt wurde. int tasterValue = -1; void setup() { //das LCD-Display hat 2 Zeilen mit maximal 16 Zeichen pro Zeile lcd.begin(16, 2); //der Index ist initial auf -1 gesetzt, //die Funktion displayMenuItem prüft anhand des Indexes und der gegebenen //Richtung welche Einträge angezeigt werden sollen displayMenuItem(true); } void loop() { //auslesen des analogen Wertes, dieser ändert sich je nach Taster tasterValue = analogRead(taster); //prüfen welcher Taster betätigt wurde switch (tasterValue) { case UP: displayMenuItem(false); break; case DOWN: displayMenuItem(true); break; case SELECT: doSomething(); break; } } //Diese Funktion zeigt zwei Daten auf dem LCD-Display an, abhängig //von dem Index und der Richtung welche navigiert werden soll. void displayMenuItem(bool directionDown) { //leeren des Displays lcd.clear(); //Zeile 2 soll den Inhalt "-ENDE-" haben wenn das Ende des Menüs erreicht wurde. String line2 = "-ENDE-"; //Wenn der Wert des Parameters //directionDown Wahr/True ist UND //der Wert vom index kleiner als die maximale Anzahl der Menüeinträge -1 ist, dann... if (directionDown && index < NUM_MENU_ITEMS - 1) { index++; } else if (!directionDown && index > 0) { index--; } //Die erste Zeile enthält den Text aus dem Menü mit dem Wert index. //Der erste Eintrag im Array hat den Eintrag 0! String line1 = menu; //prüfen ob das Ende des Menüs / Arrays erreicht wurde if (index < NUM_MENU_ITEMS - 1) { line2 = menu; } //Anzeigen der Daten auf dem Display lcd.setCursor(0, 0); lcd.print(">" + line1); lcd.setCursor(0, 1); lcd.print(" " + line2); //eine kleine Pause von 250ms um die Taster zu entprellen delay(250); } void doSomething() { //eine kleine Pause von 250ms um die Taster zu entprellen delay(250); } Mit den beiden Tasten UP & DOWN können wir nun durch das Menü navigieren. Die Taste SELECT wurde im Code bereits eingebunden, hat jedoch derzeit noch keine Funktion. Beispiel 2 - Aktivieren / Deaktivieren von LEDs über ein Menü Ein einfaches Beispiel ist das Schalten von LEDs. Im nachfolgenden Beispiel möchte ich vier LEDs über das Menü Aktivieren bzw. Deaktivieren. Statt einer LED kannst du auch ein Relais schalten und somit andere Verbraucher steuern.
LEDLCD Keypad ShieldGelbD2BlauD3RotD11GrünD12Kathode / GNDGND Der Quellcode ist etwas länger geworden da ich hier eine Struktur für die LEDs implementiert habe welche die Daten für die Pins, den aktuellen Status sowie den Menüeintrag beinhalten. struct MenuItem { int ledPin; bool ledStatus; String caption; }; Damit können wir nun über einen sprechenden Namen auf die jeweilige LED zugreifen aber auch unser Menü aufbauen. MenuItem mILedGelb = { 2, false, "LED Gelb" }; MenuItem mILedBlau = { 3, false, "LED Blau" }; MenuItem mILedRot = { 11, false, "LED Rot" }; MenuItem mILedGruen = { 12, false, "LED Gruen" }; //maximale Anzahl der Einträge im Array const int NUM_MENU_ITEMS = 4; //das Menü MenuItem menu = { mILedGelb, mILedBlau, mILedRot, mILedGruen }; Der komplette Quellcode zum steuern von LEDs über ein Menü am LCD Keypad Shield: #include //initialisieren des Displays LiquidCrystal lcd(8, 9, 4, 5, 6, 7); //die Taster sind gemeinsam über den //analogen Pin A0 angeschlossen #define taster A0 //analoge Werte der Taster const int SELECT = 640; const int LEFT = 409; const int RIGHT = 0; const int UP = 99; const int DOWN = 256; //Feld für den Wert des Tasters welcher betätigt wurde. int tasterValue = -1; //Aufbau des Menüs //aktueller Index int index = -1; //Struktur für ein Menüeintrag struct MenuItem { int ledPin; //der Pin der LED bool ledStatus; //der Status String caption; //Text für das Menü }; //initialisieren der Menüeinträge MenuItem mILedGelb = { 2, false, "LED Gelb" }; MenuItem mILedBlau = { 3, false, "LED Blau" }; MenuItem mILedRot = { 11, false, "LED Rot" }; MenuItem mILedGruen = { 12, false, "LED Gruen" }; //maximale Anzahl der Einträge im Array const int NUM_MENU_ITEMS = 4; //das Menü MenuItem menu = { mILedGelb, mILedBlau, mILedRot, mILedGruen }; void setup() { //Pins der LEDs als Ausgang definieren pinMode(mILedGelb.ledPin, OUTPUT); pinMode(mILedBlau.ledPin, OUTPUT); pinMode(mILedRot.ledPin, OUTPUT); pinMode(mILedGruen.ledPin, OUTPUT); //das LCD-Display hat 2 Zeilen mit maximal 16 Zeichen pro Zeile lcd.begin(16, 2); //der Index ist initial auf -1 gesetzt, //die Funktion displayMenuItem prüft anhand des Indexes und der gegebenen //Richtung welche Einträge angezeigt werden sollen displayMenuItem(true, false); } void loop() { //auslesen des analogen Wertes, dieser ändert sich je nach Taster tasterValue = analogRead(taster); //prüfen welcher Taster betätigt wurde switch (tasterValue) { case UP: displayMenuItem(false, false); break; case DOWN: displayMenuItem(true, false); break; case SELECT: doSomething(); break; } } //Diese Funktion zeigt zwei Daten auf dem LCD-Display an, abhängig //von dem Index und der Richtung welche navigiert werden soll. //Parameter updateOnly steuert ob der Index erhöht oder verringert werden soll, //bei true wird der Abschnitt übersprungen void displayMenuItem(bool directionDown, bool updateOnly) { //leeren des Displays lcd.clear(); //Zeile 2 soll den Inhalt "-ENDE-" haben wenn das Ende des Menüs erreicht wurde. String line2 = "-ENDE-"; if (!updateOnly) { //Wenn der Wert des Parameters //directionDown Wahr/True ist UND //der Wert vom index kleiner als die maximale Anzahl der Menüeinträge -1 ist, dann... if (directionDown && index < NUM_MENU_ITEMS - 1) { index++; } else if (!directionDown && index > 0) { index--; } } //Die erste Zeile enthält den Text aus dem Menü mit dem Wert index. //Der erste Eintrag im Array hat den Eintrag 0! MenuItem& itemLine1 = menu; //prüfen ob das Ende des Menüs / Arrays erreicht wurde lcd.setCursor(0, 1); if (index < NUM_MENU_ITEMS - 1) { MenuItem itemLine2 = menu; lcd.print(" " + itemLine2.caption + getLEDStatus(itemLine2.ledStatus)); } else { lcd.print("-ENDE-"); } //Anzeigen der Daten auf dem Display lcd.setCursor(0, 0); lcd.print(">" + itemLine1.caption + getLEDStatus(itemLine1.ledStatus)); Serial.println(itemLine1.ledStatus); //eine kleine Pause von 250ms um die Taster zu entprellen delay(250); } //Liefert anhand des boolschen Wertes einen Text //bei true wird " AN", //bei false wird " AUS" geliefert String getLEDStatus(bool status) { String result = " "; if (status == true) { result += "AN"; } else { result += "AUS"; } return result; } //Führt eine Aktion aus void doSomething() { //Wichtig ist das wir das MenuItem aus dem Array mit //einem & entnehmen, damit holen wir uns keine Kopie //sondern eine Referenz. Dieses wird benötigt, da wir //den Status der LED togglen und speichern wollen. MenuItem& item = menu; //umkehren des Status der LED item.ledStatus = !item.ledStatus; //schreiben des aktuellen Status an die LED digitalWrite(item.ledPin, item.ledStatus); //aktualisieren des Displays displayMenuItem(true, true); //eine kleine Pause von 250ms um die Taster zu entprellen delay(250); } Über das Menü können wir nun jede LED einzeln ansteuern und Aktivieren bzw. Deaktiviern. Beispiel 3 - schalten von Relais über ein Menü Ich kann quasi schon den Kommentar erahnen "Wie mache ich das mit Relais?". Daher gleich als nächstes das Beispiel mit einem Relaisshield. Zunächst passen wir die Struktur des MenuItems für eine allgemeingültige Form an. //Struktur für ein Menüeintrag struct MenuItem { int pin; //der Pin bool status; //der Status String caption; //Text für das Menü }; In meinem Fall erstelle ich zwei Menüeinträge, zum einen für eine Gartenpumpe und für eine Lampe. //initialisieren der Menüeinträge MenuItem mI1 = { 2, true, "Gartenpumpe" }; MenuItem mI2 = { 3, true, "Lampe" }; //maximale Anzahl der Einträge im Array const int NUM_MENU_ITEMS = 2; //das Menü MenuItem menu = { mI1, mI2 }; Relais haben eine besonderheit diese sind bei einem aktiven Pin deaktiviert und bei einem deaktivierten Pin aktiviert. Dazu lege ich mir eine Variable an mit welcher man dieses übersteuern kann und somit der Code wiederverwendet werden kann. bool defaultDeactive = true; Das macht es nun möglich den Code im grunde zu belassen und wir brauchen lediglich unser Menü aufbauen. #include //initialisieren des Displays LiquidCrystal lcd(8, 9, 4, 5, 6, 7); //die Taster sind gemeinsam über den //analogen Pin A0 angeschlossen #define taster A0 //analoge Werte der Taster const int SELECT = 640; const int LEFT = 409; const int RIGHT = 0; const int UP = 99; const int DOWN = 256; //Feld für den Wert des Tasters welcher betätigt wurde.
