Franzis Adventskalender fĂŒr Arduino - Tag 1
Tumblr media
Heute starten wir mit dem ersten Tag des Franzis Adventskalender fĂŒr Arduino.
Tumblr media
Franzis Adventskalender fĂŒr Arduino - Tag 1 Öffnen wir nun also das erste TĂŒrchen. Hinter dem ersten TĂŒrchen verbirgt sich ein Arduino Nano V3.
Tumblr media Tumblr media Tumblr media Tumblr media
Im Handbuch finden fĂŒr zum Tag 1, wie man diesen Mikrocontroller einrichtet und die Arduino IDE installiert. Was du noch benötigst, ist ein Micro-USB Datenkabel fĂŒr die Verbindung zum PC.
Einrichten auf einem Windows-PC
Eigentlich verbindet man den Mikrocontroller nur mit dem PC und dann wird dieser sogleich eingerichtet. Eigentlich! In meinem Fall hat sich der PC mit einem Bluescreen verabschiedet und einer IRQ Meldung, d.h. eigentlich nur das dieser Mikrocontroller einen IRQ belegen wollte, welcher bereits belegt oder reserviert ist. Okay kann passieren, Windows halt, also einmal neu starten und ein zweiter Versuch. Nun hat es funktioniert und der Mikrocontroller wurde im GerÀte-Manager erkannt.
Tumblr media
Windows GerĂ€temanager - Arduino Nano von Franzis Da ich bereits mit einigen Mikrocontrollern gearbeitet habe und somit diverse Treiber bereits installiert habe, entfiel der Schritt zum Installieren des seriellen Treibers fĂŒr den CH340G Chip.
Aufbau des Arduino Nano
Auf dem Markt gibt es diverse Arduino Nano Klone (wie auch dieser hier von Franzis), was allen ziemlich gleich ist, dass diese dasselbe Pinout haben.
Tumblr media
Pinout - Arduino Nano V3
Technische Daten des Arduino Nano V3
Den Arduino Nano habe ich bereits in sehr vielen BeitrĂ€gen auf diesem Blog verwendet und dir auch im Beitrag Arduino Nano – Übersicht dir diesen bereits vorgestellt. Auf dem Board ist ein ATMEL MEGA328P verbaut.
Tumblr media
Hier nun der VollstĂ€ndigkeit halber die technischen Daten zu diesem Mikrocontroller: LĂ€nge45 mmBreite18 mmGewicht7 gFlash Speicher32 KB (von denen 2 KB fĂŒr den Bootloader reserviert sind)SRAM2 KBEEPROM1 KBCPU Taktgeschwindigkeit16 MHzBetriebsspannung5 VEingangsspannung7 V bis 12 VStromaufnahme19 mAmax. StromstĂ€rke pro I/O Pin40 mAdigitale EingĂ€nge / AusgĂ€nge22digitale PWM AusgĂ€nge6analoge EingĂ€nge / AusgĂ€nge8
Installieren der Arduino IDE 2.0
Im Handbuch wird die Arduino IDE in der Version 2.0.0 Beta-3 dargestellt, mittlerweile haben wir eine offizielle Version zur VerfĂŒgung. Diese beiden Versionen sind vom Aufbau her sehr unterschiedlich, daher zeige ich dir in den nĂ€chsten Tagen, wie die Schaltungen in der neuen Version programmiert werden.
Tumblr media
Arduino IDE 2.0.0 Die aktuelle Version kannst du unter https://www.arduino.cc/en/software herunterladen, die Installation ist denkbar einfach, denn man muss lediglich dem Wizard folgen.
Aufbau der Arduino IDE
Die Arduino IDE hat eine Toolbar, in welcher du die SchaltflÀchen findest, welche du wohl am meisten benötigst.
Tumblr media
v.l.n.r: - Verify, - Upload, - Debug, - ausgewĂ€hlter Mikrocontroller, - Serial Plotter, - Serial Monitor Das Debuggen also das PrĂŒfen von Code wĂ€hrend der AusfĂŒhrung unterstĂŒtzt nicht jeder Mikrocontroller, auch wĂŒrde dieses fĂŒr diese BeitrĂ€ge viel zu weit gehen.
Programmieren des Arduino Nano
Im ersten TĂŒrchen war lediglich der Mikrocontroller, jedoch kann man selbst mit diesem schon einiges machen. Auf dem Board ist zbsp. eine kleine SMD LED verbaut, welche wir zum Blinken, Faden (langsames Auf-/Ableuchten) bringen können.
AuswÀhlen des Mikrocontrollers
Bevor wir einen Code schreiben oder hochladen können, mĂŒssen wir den Mikrocontroller auswĂ€hlen. Dazu navigieren wir ĂŒber das HauptmenĂŒ von Tools > Board: xyz > Arduino AVR Boards und wĂ€hlen dort den Eintrag "Arduino Nano" aus. Danach wĂ€hlen wir noch den Port aus und schon ist die Einrichtung fertig.
Tumblr media
AuswĂ€hlen des Mikrocontrollers Arduino Nano in der Arduino IDE "Hello World!" auf der seriellen Schnittstelle Starten möchte ich jedoch zunĂ€chst mit einem kleinen "Hello World!" Beispiel, in welchem wir Text auf der seriellen Schnittstelle ausgeben. Diesen Text können wir uns in der Arduino IDE anzeigen lassen, aber auch andere Tools welche Daten von der seriellen Schnittstelle lesen können wie Putty, MobaXTerm können diese anzeigen. Der Vorteil bei der Arduino IDE ist jedoch, dass wir dafĂŒr kein extra Tool benötigen. void setup() { // beginn der seriellen Kommunikation mit 9600 baud Serial.begin(9600); } void loop() { // ausgeben der Textzeile "Hello World!" // auf der seriellen Schnittstelle Serial.println("Hello World!"); // eine kleine Pause von 500 ms delay(500); } Wenn das kleine Programm hochgeladen wurde, sehen wir in der Konsole folgende Ausgabe. Aus diesem Text können wir entnehmen, wie viel Speicher von unserem Programm belegt wird und wie viel noch frei ist. Der Sketch verwendet 1634 Bytes (5%) des Programmspeicherplatzes. Das Maximum sind 30720 Bytes. Globale Variablen verwenden 200 Bytes (9%) des dynamischen Speichers, 1848 Bytes fĂŒr lokale Variablen verbleiben. Das Maximum sind 2048 Bytes. Ausgabe der Textzeile "Hello World!" im seriellen Monitor der Arduino IDE.
Tumblr media
Blinken der onboard SMD LED Die kleine SMD onboard LED kannst du ĂŒber den digitalen Pin D13 oder der Konstante LED ansteuern. // onboard LED am digitalen Pin D13 angeschlossen // ansteuern ĂŒber die Pin Nummer // #define led 13 // int led = 13; // ansteuern ĂŒber einer Konstanten #define led LED_BUILTIN void setup() { // Definieren das der Pin der LED als // Ausgang dient. pinMode(led, OUTPUT); } void loop() { // Pin der LED auf HIGH setzen digitalWrite(led, HIGH); // eine kleine Pause von 500 ms. delay(500); // Pin der LED auf LOW setzen. digitalWrite(led, LOW); // eine kleine Pause von 500 ms. delay(500); } Wenn wir den Code nun auf den Mikrocontroller ĂŒbertragen, dann blinkt die kleine, orange SMD LED auf der Platine im Intervall von 500 ms.

v2.x.x. is the worst thing they couldve done to the arduino ide
not only did it fuck up my code back when it first updated like 6m ago, but im now finding out they changed the serial plotter to only show 50 points!?
i need to make graphs from the serial output and i need them yesterday, i tried 3rd party programs and not a single one worked cause theyre all in java or python or some such shit
ill have to roll back tmrw and deal w whatever shit that unleashes, fmsbl i do not have time for this i lost the whole day to this

While browsing in a thrift store some months ago, I found a selection of stepper motors. I picked up some matching NEMA 17 motors, the size you find in 3d printers, but also two NEMA 08s.
Tumblr media
The 08 refers to the size. NEMA specifies the size numbers as the size of the faceplate (around the motor's shaft), measured in tenths of an inch. So a NEMA 08 motor's face is 0.8" across — nicely compact, and I plan to make a little pen plotter with these.
The trouble starts when you try to make them run. These aren't "hobby motors", where if you stick one wire on either end of a battery, it runs. Stepper motors have, at minimum, four wires, so that's not going to work. You can look at a good description of how they work on Wikipedia, but suffice it to say that the easiest way to get real control on these is to use a microcontroller and a motor driver board. The microcontroller is a tiny computer that tells the motor driver how and when to move the motor, and the driver translates that into the proper voltages on the right wires.
Fortunately, I have both of these. For a microcontroller, I have an Arduino — just an old one I had lying around, which is plenty — and for a motor driver, I have a Seeedstudio Motor Shield, which plugs into the Arduino and provides places to connect the stepper motor and the power to drive it (I got these at Radio Shack, which may indicate just how long I've had them). Unfortunately, a Motor Shield can only drive a single stepper, and I want to drive both of them. I could buy a driver board to run both motors, but I don't really want to spend extra money right now. I do have a second Motor Shield, so the quickest thing would be to use two Arduinos, put a Motor Shield on each one, and have the two microcontrollers coordinate somehow. But that's much more complicated than running both motors off one micro.
Tumblr media
What I arrived at is the above. A Motor Shield uses pins 8, 11, 12, and 13 to drive the motor. But each Motor Shield also has what Seeed calls Grove connectors along the side, which let you get to the pins on the Arduino that the shield isn't using. So I've wired some of those to the operative pins on the second shield. So when the standard setup to use a Motor Shield goes like:
StepperMotor myStepper(stepsInARevolution, 8, 11, 12, 13);
I can turn around and say:
StepperMotor myStepper1(stepsInARevolution, 8, 11, 12, 13);
StepperMotor myStepper2(stepsInARevolution, 2, 3, 4, 5);
and behave as though I had a shield that could run both at once.

Two Arduinos are used to control this DIY three-axis CNC plottee
We’ve seen a number of homemade CNC machines throughout the years, but Tuenhidiy’s build — made from some discarded materials — is no less impressive. This unique CNC plotter features a frame cleverly constructed out of two wooden wine boxes, which appear to be the perfect size with space for an Y-axis bed and an upright structure that actuates X movements. For the Z component, a pen is lifted using parts from a recycled CD player drive.
Electronics-wise, the project is also quite interesting as it employs servos rather than steppers for its X and Y axes. Actuation is handled by an Arduino Uno with pre-installed GRBL firmware and a CNC shield, which sends commands to an Arduino Mega running custom firmware. The Mega — plus a custom adapter board and an L293D shield — takes care of PID control for the motors.
More details on the machine can be found in Tuenhidiy’s write-up, and you can see it demonstrated in the video below.

AZ-Envy - auslesen der Sensordaten
Tumblr media
In diesem Beitrag möchte ich dir zeigen, wie du die Sensordaten des AZ-Envy auslesen kannst.
Tumblr media
Den AZ-Envy habe ich dir bereits im Beitrag Vorstellung AZ-Envy vorgestellt und gezeigt, wie dieser angeschlossen und programmiert wird.
Tumblr media Tumblr media
Auf dem AZ-Envy ist ein ESP8266 verbaut und zwei Sensoren. Der SHT30 Sensor dient fĂŒr die Erfassung von Luftfeuchtigkeit und Temperatur sowie ein MQ-2 fĂŒr LuftqualitĂ€t.
Benötigte Ressourcen
Wenn du dieses Board wie nachfolgend programmieren und die Sensordaten vom AZ-Envy auslesen möchtest, dann benötigst du: - einen AZ-Envy, - ein Micro-USB Datenkabel, - ein FTDI232 Adapter, - ein Mini-USB Datenkabel, - drei Breadboardkabel, weiblich-weiblich, 10 cm
Anschluss des FTDI232 Adapters an den AZ-Envy
Der FTDI232 Adapter wird mit drei Breadboardkabel mit dem AZ-Envy verbunden. AZ-EnvyFTDI232 AdapterRXRXTXTXGNDGND ZusÀtzlich musst du das Board mit einem Micro-USB-Kabel verbinden, damit dieser Strom erhÀlt.
Tumblr media
Board AZ-Envy mit FTDI232 Adapter
Probleme mit dem Sensor MQ-2 & SHT30
Der LuftqualitĂ€tssensor MQ-2 wird im Betrieb sehr warm und durch die ungĂŒnstige Platzierung zur NĂ€he des Sensors SHT30 erhĂ€ltst du von letzterem ggf. sehr ungenaue Werte.
Tumblr media
Temperatur des MQ-2 Sensors im Betrieb In einigen Foren wurde bereits darĂŒber sehr ausgiebig diskutiert. Eine Lösung dazu ist den Sensor SHT30 abzuschirmen, in der Platine ist eine kleine Rinne eingelassen, in welche man ein Schild einlassen kann und somit zumindest etwas WĂ€rme vom Sensor ableiten kann.
Programmieren in der Arduino IDE
Wie du den Mikrocontroller in der Arduino IDE einrichtest, habe ich dir bereits im oben verlinkten Beitrag gezeigt. Im nachfolgenden YouTube-Video zeige ich dir, wie du am AZ-Envy die Sensordaten auslesen kannst. https://youtu.be/E8-UMpHXCOw Bibliotheken fĂŒr die verbauten Sensoren FĂŒr das Auslesen der Sensoren benötigen wir zwei Bibliotheken, diese können wir ĂŒber die Shopseite von AZ-Delivery zum Board als ZIP-Datei herunterladen und ĂŒber Sketch > Include Library > Add .ZIP Library in der Arduino IDE importieren. Auslesen der Luftfeuchtigkeit und Temperatur vom SHT30 Sensor Der Sensor SHT30 liefert wie erwĂ€hnt die Temperatur sowie die relative Luftfeuchtigkeit. Nachfolgend nun ein kleines Programm, welches diese Daten ausließt und auf der seriellen Schnittstelle ausgibt. //Bibliothek zum auslesen der Sensorwerte //vom SHT30 Sensor #include //instanziieren eines Objektes vom Typ SHT3X //mit der I2C Adresse 0x44 SHT3X sht30(0x44); void setup() { //beginn der seriellen Kommunikation mit 9600 baud Serial.begin(9600); } void loop() { //Wenn die kommunikation per I2C mit dem Sensor //erfolgreich war, dann... if (sht30.get() == 0) { //lesen der Temperatur in Grad Celsius float temperature = sht30.cTemp; //lesen der rel. Luftfeuchtigkeit in % float humidity = sht30.humidity; //ausgeben der Temperatur Serial.print("Temperatur: "); Serial.print(temperature); Serial.println("°C"); //ausgeben der rel. Luftfeuchtigkeit Serial.print("rel. Luftfeuchtigkeit: "); Serial.println(humidity); Serial.println("%"); } //eine kleine Pause von 5 Sekunden delay(5000); }
Tumblr media
Auslesen der LuftqualitĂ€t des MQ-2 Sensors Der LuftqualitĂ€tssensor MQ-2 wird im Betrieb warm und liefert je lĂ€nger die LĂ€uft genauere Messwerte, daher wĂŒrde ich dir empfehlen diesen fĂŒr min. 1h laufen zu lassen, bevor du die echten Werte verwenden kannst. //LuftqualitĂ€tssensor MQ-2 ist //am analogen Pin A0 angeschlossen #define MQ2Pin A0 void setup() { //beginn der seriellen Kommunikation mit 9600 baud Serial.begin(9600); //analogen Pin als Ausgang definieren pinMode(MQ2Pin, INPUT); } void loop() { //lesen des analogen Wertes int sensorValue = analogRead(MQ2Pin); //Ausgeben des gelesenen Wertes auf //der seriellen Schnittstelle Serial.print("LuftqualitĂ€t: "); Serial.print(sensorValue); Serial.println("ppm"); //eine kleine Pause von 2 Sekunden delay(2000); }
Tumblr media
Wert im seriellen Plotter der Arduino IDE visualisieren
Die Arduino IDE verfĂŒgt ĂŒber einen seriellen Plotter, welchen wir nutzen können, um Sensorwerte in einem Liniendiagramm zu visualisieren.
Tumblr media
Dazu mĂŒssen wir die Legende und die Werte in einem bestimmten Format auf der seriellen Schnittstelle ausgeben. #include SHT3X sht30(0x44); #define MQ2Pin A0 float temperature = 0; float humidity = 0; void setup() { Serial.begin(9600); pinMode(MQ2Pin, INPUT); } void loop() { if (sht30.get() == 0) { temperature = sht30.cTemp; humidity = sht30.humidity; } int sensorValue = analogRead(MQ2Pin); Serial.print("Temperatur(°C):"); Serial.print(String(temperature, 2)); Serial.print("t"); Serial.print("rel.Luftfeuchtigkeit(%):"); Serial.print(String(humidity, 2)); Serial.print("t"); Serial.print("LuftqualitĂ€t(analog):"); Serial.print(String(sensorValue, DEC)); Serial.println(); delay(2000); }
Download der Programme
Hier nun die gezeigten Programme zum einfachen Download als ZIP-Datei fĂŒr die Arduino IDE.

DIY ECG Part 4
Part 1 Part 2 Part 3
Software
The last part of this tutorial is about the software needed to display the ECG signal on your computer. This guide is based on the tutorial found on Sparkfun (https://learn.sparkfun.com/tutorials/ad8232-heart-rate-monitor-hookup-guide/all). If you are stuck at some point in this tutorial, I would recommend you to read the section on Sparkfun, as their guide is more detailed.
Three pieces of software are needed:
Arduino IDE (https://www.arduino.cc/en/Main/Software)
Processing IDE (https://processing.org/download/)
the adapted code (https://mega.nz/#!9roDGAha!21aKPDvBIuEhjTG9IAFJlwZZrH9vBTv6E5AQN-6GP2g)
Install the version of the Arduino IDE and Processing IDE for your operating system. For the Arduino board to be recognized by Windows, one needs to install an additional driver. Refer to this site for the detailed installation instructions. I would also recommend you to get familiar with the interface and try to upload the first demo program as described under "Launch and Blink!" on the same page. Note: for Tools->Board you would choose "Arduino Nano", for Tools->Processor "ATmega 328p (old bootloader)" and for Tools->Port you would try out all options until it works!
If that worked, we can now upload the code for the ECG. Extract the zip archive with the code and open up "Heart_Rate_Display_Arduino.ino" in the "Heart_Rate_Display_Arduino" folder with the Arduino IDE. Make sure the options under Tools are set to the same values as before. Note: The port can change over time, especially if unplugging the Arduino at some time! The ECG can already be tested. Make sure, the ECG electrodes are placed correctly on your body (see last part 3 of this tutorial). Now open the Serial plotter under the Tools menu in the Arduino IDE. The "baud rate" should be set to the value 19200. This is the rate at which Arduino and computer communicate. If everything was done correctly, you should already see something very much like an ECG!
For a fancier output, open up the Processing IDE. Open the "Heart_Rate_Display_Processing.pde" file from the "Heart_Rate_Display_Processing" folder. For sound output (yes, the beeping of the ECG!) an extra programming library is needed. Go to Tools->Add Tool and there to the Libraries tab. Search for "minim" and click on the Install button on the lower left corner of the window. After it is installed, close the window. Then run the code by pressing the Play button in the main window. Probably it will crash on the first try. Increment the zero found in the code at the line with "myPort = new Serial(this, Serial.list()[0], 19200);" and try again. By doing so, one searches for the Arduino as before in the Arduino IDE. Repeat the process until it works. The correct number should be probably under 10.
If you did everything correctly, the output should look somewhat like this:
vimeo
I wish you a lot of fun with your DIY ECG monitor!

Artist Statement
‘Mutate’ is a dynamic installation which reacts to the user’s kinetic energy (input) and translates this raw data to produce the movement of an XY plotter (process) which creates an interactive display of articulate and engaged motions, presented through a magnetic ferrofluid (output). We often see ourselves through mirrors, photos, and reflective surfaces, but something that we tend to overlook is the physical representation of ourselves through movement and energy. Everyone’s kinetic energy is different, and that is what ‘Mutate’ aims to portray.
The use of a magnetic substance is also an enigmatic concept, as the earth’s core contains a geomagnetic field that extends from the earth’s interior out into space. For the user to be able to control such a cryptic substance through their own kinetic energy is a complex experience made possible through ‘Mutate’. The design is produced through Arduino software, which uses Grbl and Gcode to control the movement of an XY plotter. An augmented visualisation is created through the input of kinetic energy, which is captured through a PIR motion sensor and allows for the mutation and movement of a magnetic ferrofluid - encased within an acrylic tank.
