Arduino to P5js & Potentiometers

Circuit Description:

In this project, I used a potentiometer connected to an Arduino to control the horizontal movement of a circle in a p5.js sketch. The potentiometer sends a changing voltage to the Arduino depending on how you turn the knob. This voltage is read by the Arduino as a number using analogRead(). The Arduino then sends this number to the computer through serial communication.

In the p5.js sketch, the computer listens for that data using the p5.serialport library. When new data arrives, the sketch receives the value and maps it to the width of the canvas.

So as I turn the potentiometer knob, the circle on the screen moves left or right smoothly, depending on the input. This makes the potentiometer act like a controller for the position of the shape.

Code:

void setup() { // initialize serial communication at 9600 bits per second: Serial.begin(9600); }

// the loop routine runs over and over again forever: void loop() { // read the input on analog pin 0: int sensorValue = analogRead(A0); // print out the value you read: Serial.println(sensorValue); delay(1); // delay in between reads for stability }

Lab 5: Arduino and P5.js :)

The objective of this lab was to establish serial communication between an Arduino and a P5.js sketch using the P5.SerialControl library. The goal was to read analog input from a potentiometer (or other sensor) and use this data to manipulate a sound parameter in P5.js. This experiment introduces the concept of serial communication and demonstrates how real-world input can create interactive experiences in a digital environment. The materials used were Arduino Uno Hardware , Breadboard, Jumper wires, Potentiometer (10kΩ) Arduino IDE software & P5.js web editor and installed P5.SerialControl library for P5.js (Darwin version).

Descriptive Circuit Overview:

As said above, the circuit consisted of an Arduino Uno, a 10kΩ potentiometer, and a serial connection to a P5.js sketch. The potentiometer is wired with:

The Potentiometer placed in the middle of the bread board.

Ground and power wires connected across the bottom edge of the breadboard.

The middle pin connected to A1 (analog input pin on the Arduino).

One outer pin connected to 5V power in the Arduino.

The other outer pin connected to ground (GND) in the Arduino.

This setup allows the potentiometer to function as a voltage divider. When the potentiometer is turned, the resistance changes, changing the voltage received by the Arduino’s analog input pin. The Arduino was able to read this voltage using the analogRead() command, converted it into a numerical value (range: 0 to 1023), and sent this data to the P5.js sketch over the serial communicator (P5.js Serial.Control).

Schematic:

Code Explanation Overview-Arduino:

The Arduino code initializes one analog pin, A1, to read input from the potentiometer. The values are then sent via the Serial.print() function in a comma-separated format, allowing P5.js to parse them correctly.

Pin Setup: The potentiometer’s pin is set as an input using pinMode(sensorPin, INPUT).

Analog Reading: The values A1 are continuously read using analogRead(sensorPin).

Serial Communication: The values are sent over the serial port using Serial.println(sensorValue);. The comma serves as a delimiter to separate multiple values.

This ensures that the final P5.js sketch can properly interpret and map the incoming data, which would be displayed in the serial console/monitor of the Arduino Uno, Serial Controller, and P5.js web editor console. In other words, the serial controller allows the code to be communicated from the Arduino software to the P5.js. The code is below:

int sensorValue = 0;

int sensorPin = A1;

void setup() {

// put your setup code here, to run once:

pinMode(sensorPin, INPUT);

Serial.begin(9600);

}

void loop() {

// put your main code here, to run repeatedly:

sensorValue = analogRead(sensorPin);

Serial.println(sensorValue);

}

Code Explanation Overview-P5.js:

The P5.js sketch establishes serial communication with the Arduino and reads the sensor data to control a visual representation through the resistance of the potentiometer.

Serial Communication Setup: The script initializes a serial connection using serial = new p5.SerialPort();, lists available ports, and attempts to open the correct one.

Data Reception: The function serial.on('data', gotData); listens for incoming serial data and stores it in a variable.

Data to Visuals: The sensor values are used to control the size of a circle on the canvas (circle(20,20,latestData);) in function draw().

Display of Values: The latest received data is displayed on the screen using text(latestData, 10, 10).

The code is below:

let serial; let latestData = "waiting for data";

function setup() { createCanvas(windowWidth, windowHeight);

serial = new p5.SerialPort();

serial.list(); serial.open('/dev/tty.usbmodem1301');

serial.on('connected', serverConnected);

serial.on('list', gotList);

serial.on('data', gotData);

serial.on('error', gotError);

serial.on('open', gotOpen);

serial.on('close', gotClose); }

function serverConnected() { print("Connected to Server"); }

function gotList(thelist) { print("List of Serial Ports:");

for (let i = 0; i < thelist.length; i++) { print(i + " " + thelist[i]); } }

function gotOpen() { print("Serial Port is Open"); }

function gotClose(){ print("Serial Port is Closed"); latestData = "Serial Port is Closed"; }

function gotError(theerror) { print(theerror); }

function gotData() { let currentString = serial.readLine(); trim(currentString); if (!currentString) return; console.log(currentString); latestData = currentString;

}

function draw() { background(255,255,latestData); fill(0,0,0); text(latestData, 10, 10);

fill(5,200,5); circle (20, 20 latestData);

// Polling method /* if (serial.available() > 0) { let data = serial.read(); ellipse(50,50,data,data); } */ }

Lastly, into the P5.js helm library file of the sketch, we put this P5.js Port Control Script link library in it as well:

<script language="javascript" type="text/javascript" src="https://cdn.jsdelivr.net/npm/p5.serialserver@0.0.28/lib/p5.serialport.js"></script>

Observations/Analysis:

When manipulating the potentiometer, the values ranged from 0 to 1023 (Arduino’s 10-bit ADC resolution). These values were mapped in P5.js to control the size of the circle in real-time, and went further to change the background color as well. The movement of the shape corresponded smoothly to changes in sensor input, proving the effectiveness of serial communication.

If we had applied the data to sound manipulation, the potentiometer’s values could have been mapped to control frequency, volume, or panning. The map() function would be used to scale the 0-1023 range into an appropriate audio parameter range in P5.js.

A demo video of the outcome is below:

Challenges and Troubleshooting:

Some challenges encountered included:

Serial Port Connection Issues: Initially, P5.js could not detect the correct serial port. This was resolved by having manually specifying the port (serial.open('/dev/tty.usbmodem1301');) in the script. This required a lot of troubleshooting code and hardware at first.

Conclusion:

This lab demonstrated how Arduino and P5.js can communicate through serial data, allowing physical input to control digital outputs. The way. that the potentiometer was able to change the size of the circle, isthe same way it can be used to turn vilume up and down on a device. Understanding serial communication opens up possibilities for interactive installations, such as motion-sensitive visuals or audio-controlled audio experiences. This aspect introduces new ways to map sensor input to audio-visual feedback, an essential skill in creative coding and physical computing.

In the future, this technique could be expanded by integrating multiple sensors and including the synthesis of sound assets to creat an immersive experience.

...Or it could be used in part to make a DIY iPod.

Midterm Project: The Video Game Controller

Introduction:  The game initially was supposed to be a game where the objective is to catch water in a bucket for a town experiencing a drought

Sensor Rationale: My sensor was the PIR motion sensor, the rationale was to resemble a VR game where the user would be controlling the direction of the bucket depending on which sensor they activated

Controller Design & Construction: To set up two PIR motion sensors with my Arduino and breadboard, I started by gathering everything I needed: an Arduino board, two PIR sensors (like the HC-SR501), a breadboard, and some jumper wires. Each PIR sensor has three pins (VCC for power, GND for ground, and OUT for the signal). Since the sensor pins are small and not ideal for directly plugging into a breadboard, I decided to solder jumper wires directly to the pins. I soldered one wire to each pin and then I plugged them into the breadboard . I connected both VCC wires to the 5V pin on the Arduino and both GND wires to the Arduino’s GND pin. Then, I connected the OUT wire from the first PIR sensor to digital pin 7 and the OUT wire from the second sensor to digital pin 4.

Arduino Code : 

const int pirPin1 = 5;  // First PIR sensor connected to pin 7

const int pirPin2 = 4;  // Second PIR sensor connected to pin 8

int pirState1 = LOW;    // State of PIR sensor 1

int pirState2 = LOW;    // State of PIR sensor 2

int lastPirState1 = LOW; // Last state of PIR sensor 1

int lastPirState2 = LOW; // Last state of PIR sensor 2

void setup() {

  pinMode(pirPin1, INPUT);  // Set PIR sensor 1 pin as input

  pinMode(pirPin2, INPUT);  // Set PIR sensor 2 pin as input

  Serial.begin(9600);       // Start serial communication at 9600 baud rate

}

void loop() {

  pirState1 = digitalRead(pirPin1);  // Read state of PIR sensor 1

  pirState2 = digitalRead(pirPin2);  // Read state of PIR sensor 2

  Serial.print(pirState1);

  Serial.print (",");

  Serial.println(pirState2);

  // Save the current state as the last state for the next loop

  lastPirState1 = pirState1;

  lastPirState2 = pirState2;

  // Delay between readings to stabilize sensor input

}

P5.js Game Code (Well-Commented): 

let serial; let latestData = "waiting for data"; // To hold the PIR sensor data

// Game variables let basketX, basketY, basketWidth, basketHeight; let fallingRaindrops = []; let score = 0;

let cloudPositions = []; // Store cloud positions for moving clouds

let targetX = 0; // Target x position for sensor 1 (smooth movement) let targetSpeed1 = 0.1; // Smooth speed for sensor 1 (change this value for more smoothness) let targetSpeed2 = 2; // Slower speed for sensor 2 (change this value for slower movement)

function setup() { createCanvas(windowWidth, windowHeight);

// Initialize the serial object for Arduino serial = new p5.SerialPort();

// List all available serial ports serial.list();

// Open the serial port (replace 'COM5' with your correct port) serial.open('COM5');

// Register event handlers for serial communication serial.on('connected', serverConnected); serial.on('list', gotList); serial.on('data', gotData); serial.on('error', gotError); serial.on('open', gotOpen); serial.on('close', gotClose);

// Set initial values for the basket (bucket) basketX = width / 2; basketY = height - 50; basketWidth = 100; basketHeight = 40;

// Initial raindrop setup setInterval(generateRaindrop, 1000); // Add a new raindrop every second

// Initialize cloud positions for (let i = 0; i < 5; i++) { cloudPositions.push({ x: random(width), y: random(height / 2), // Clouds stay at the top part of the screen speed: random(0.5, 1.5) }); } }

function serverConnected() { print("Connected to Server"); }

function gotList(thelist) { print("List of Serial Ports:"); for (let i = 0; i < thelist.length; i++) { print(i + " " + thelist[i]); } }

function gotOpen() { print("Serial Port is Open"); }

function gotClose() { print("Serial Port is Closed"); latestData = "Serial Port is Closed"; }

function gotError(theerror) { print(theerror); }

function gotData() { let currentString = serial.readLine(); // Read incoming data from the serial port if (currentString) { currentString = currentString.trim(); // Trim the string properly if (currentString) { console.log("Received data:", currentString); // Debug: show received data latestData = currentString; // Update the latest data received ("0,0", "1,0", "0,1", "1,1") } } }

function draw() { // Draw the background as a cloudy town drawCloudyTownBackground();

// Draw the bucket (using a rounded rectangle and an ellipse for the base) fill(255, 0, 0); noStroke();

// Draw the bottom of the bucket as a half ellipse arc(basketX + basketWidth / 2, basketY + basketHeight / 2, basketWidth, basketHeight, 0, PI, CHORD);

// Draw the top of the bucket as a rectangle (body) rect(basketX, basketY - basketHeight / 2, basketWidth, basketHeight / 2);

// Update basket movement based on PIR sensor input updateMovement();

// Draw and update raindrops for (let i = fallingRaindrops.length - 1; i >= 0; i--) { let raindrop = fallingRaindrops[i]; fill(0, 0, 255); // Draw the raindrop as an ellipse with more vertical elongation ellipse(raindrop.x, raindrop.y, raindrop.sizeX, raindrop.sizeY); raindrop.y += raindrop.speed; // Make the raindrop fall// Check if the raindrop hits the bucket if (raindrop.y + raindrop.sizeY / 2 >= basketY && raindrop.x > basketX && raindrop.x < basketX + basketWidth) { score++; // Increment score when a raindrop is caught fallingRaindrops.splice(i, 1); // Remove the raindrop after it is caught } // If the raindrop falls out of the screen, remove it if (raindrop.y > height) { fallingRaindrops.splice(i, 1); }

}

// Display score fill(0); textSize(24); text("Score: " + score, 10, 30); }

// Function to update movement based on PIR sensor data function updateMovement() { if (latestData) { // Parse the latest data to get pirState1 and pirState2 let states = latestData.split(","); if (states.length < 2) return; // Ensure there are two elements in the arraylet pirState1 = int(states[0].trim()); // First PIR sensor state let pirState2 = int(states[1].trim()); // Second PIR sensor state // Debugging output to confirm sensor values console.log("1", pirState1, "2", pirState2); // Update basket movement based on sensor states if (pirState1 === 1) { // Move basket to the right if motion is detected on sensor 1 basketX += 10; } if (pirState2 === 1) { // Move basket to the left if motion is detected on sensor 2 basketX -= 10; } // Prevent the basket from moving off the canvas basketX = constrain(basketX, 0, width - basketWidth);

} }

// Function to generate a falling raindrop at a random x position function generateRaindrop() { let raindrop = { x: random(width), y: 0, // Start from the top sizeX: random(10, 15), // Random width for raindrop sizeY: random(20, 40), // Random height for raindrop (more elongated) speed: random(3, 6) // Falling speed }; fallingRaindrops.push(raindrop); }

// Function to draw a cloudy town background function drawCloudyTownBackground() { // Draw sky background(135, 206, 235); // Light blue sky color

}

// Draw the city skyline (simple buildings) fill(50, 50, 50); // Dark gray for buildings rect(0, height - 150, 100, 150); // Building 1 rect(150, height - 200, 80, 200); // Building 2 rect(250, height - 180, 100, 180); // Building 3 rect(400, height - 250, 120, 250); // Building 4 rect(550, height - 160, 90, 160); // Building 5 }

Communication Protocol Details: This p5.js code connects to an Arduino using a serial port to receive live data, like numbers from sensors. It uses the p5.SerialPort() library to open the connection (on COM5) and listen for different events, like when the connection is opened, closed, or when new data arrives. When the Arduino sends data, the program reads it as a line of text, removes any extra spaces, and splits the text into two values using a comma. These values are saved as value0 and value1, which can be used in the draw() function to control what’s shown on the screen—like the position or behavior of shapes. This setup lets the webpage respond to what the Arduino senses in real time.

User Instructions: Each motion sensor determines if the bucket moves left, right, or remains stagnant. Using the left sensor, move your hand in front of it to move the bucket to the left. Using the right sensor, move your hand in front of it to move the bucket to the right. If both sensors are activated at the same time, the bucket will stay in the place it is in until one sensor halts detection.

Challenges & Solutions: Challenges included setting up the sensor and activating it. The PIR motion sensors are sensitive so trying to get them to turn off and on was a difficult task. However, I managed to tweak the settings to make the time and sensitivity low. However, that also made the sensor delayed, resulting in the reaction time glitchy in the game.

Future Enhancements: Soldering from the beginning and making sure my code is as simple as possible would help me in the future. I think also changing the game could make more sense for the sensor.

Conclusion: I learned a lot in the end, and even used AI to help me with code and wiring. Next time, I hope to use my skills to develop more complex code for p5.js and Arduino so the sensor can be used for a variety of games.

Chrome 100 with security updates released

Google released Chrome 100 Stable for all supported desktop operating systems on March 29, 2022. The new release is also available for the extended channel for Windows and Mac. The extended stable version skips all odd-numbered version releases.

Chrome 100 is a major milestone release, but an unspectacular one as it does not introduce major changes to the web browser. The new version is available already. Chrome users may load chrome://settings/help to display the current version and download the new release if it has not been downloaded and installed already. Selecting Menu > Help > About Google Chrome opens the same page.

Google Chrome 100 is a security update release first and foremost. The Chrome releases blog reveals that the release contains 28 security fixes, many of which have been reported by third-party security researchers. The highest severity rating is high and none of the issues appear to be exploited in the wild currently, as Google mentions this usually in the announcement.

As far as non-security features are concerned, there are not that many. Chrome 100 updates the parsing of cookie strings by allowing cookie domain attributes to be set to empty strings. Chrome did not handle these according to the specification up until now.

There is also a new multi-screen window placement API to better support multi-screen devices. Google lists a number of use cases for the new capabilities:

Slideshow app presents on a projector, shows speaker notes on a laptop screen.

Financial app opens a dashboard of windows across multiple monitors.

Medical app opens images (e.g. x-rays) on a high-resolution grayscale display.

Creativity app shows secondary windows (e.g. palette) on a separate screen.

Conference room app shows controls on a touch screen device and video on a TV.

Multi-screen layouts in gaming, signage, artistic, and other types of apps.

Site optimizes content and layout when a window spans multiple screens.

Here is a list of the remaining additions in Chrome 100:

The Digital Goods API is now available by default. It is an API for “querying and managing digital products to facilitate in-app purchases from web applications, in conjunction with the Payment Request API (which is used to make the actual purchases)”.

HIDDevice forget() is a new method that developers may implement to “revoke a permission to a HIDDevice that was granted by a user”.

Markup based Client Hints delegation for third-party content. which supports “content negotiation use cases such as differential serving of variable fonts, color vector fonts, responsive images, and other third-party content which requires client information lost by user agent reduction”.

SerialPort integration with WritableStream controller AbortSignal.

TLS ALPN extension in wss-schemed WebSockets connections.

Web NFC: NDEFReader makeReadOnly().

WebTransport serverCertificateHashes option.

mix-blend-mode: plus-lighter.

AbortSignal.prototype.throwIfAborted.

Capability Delegation allows “a frame to relinquish its ability to call a restricted API and transfer the ability to another (sub)frame it trusts”.

Chrome 100 is the last version of the browser that supports the full user-agent string. Google plans to reduce the user-agent string of the browser from April 19, 2022 on.

Now You: did you install the new version?

Server-side Development with NodeJS

As you build your web application, you necessarily make a series of foundational decisions that will impact the entire architecture of your applications. One of these core decisions is where to implement rendering logic in your application. This is where Node.js comes into the picture.

What is Node.js?

Node.js is a tool written in C, which allows you to use JavaScript on the server-side that lets you effortlessly develop fast and scalable web applications. It utilizes an event-driven, non-blocking I/O model that makes it lightweight, efficient, and excellent for data-intensive real-time applications that run across shared devices.

What is Node.js used for?

Node.js is used for building various business solutions. Here is a sample list of them, in reality the list is longer, much longer.

1. Backend for Social Media Networking

2. Single-page Application

3. Chat Application

4. Data Streaming

5. Backends and servers

6. Developing APIs

7. Microservices

8. Scripting and Automation

What makes Node.js special?

1. Scalability: Node.js applications are easily scalable, vertically and horizontally. While vertical scaling lets you add more support to the current nodes, horizontal scaling allows you to add new nodes faster.

2. High Performance: High performance is achieved by knowing how to take advantage of every aspect of the hardware, helping memory management act at its best, and correctly deciding how to architect a complex application.

Enterprises that use Node.js

Let's dive into the remarkable realm of Node.js

Unlike the regular web-serving technique, where each call creates a new thread obstructing the system RAM, Node.js operates on a single thread. This enables it to support thousands of concurrent connection handling event loops.

A sneak peek into the areas where Node.js can be used

Use Case 1: Data Streaming

The Problem:

An average consumer spends 40 hours per week watching video content. The gap between Traditional TV and its consumers is growing day by day.

The Solution:

A video streaming solution can be built leveraging the data streaming capability of Node.js. Data Streaming with Node.js is 25% more convenient than traditional means.

How?

The process of sending data is divided into small chunks that are sent to the front-end piece by piece, instead of a huge single package.

Use Case 2: Big Data & Analytic

The Problem:

Trying to deal with large data in a browser is troublesome and affects user experience.

The Solution:

Node.js streams ensure data flow from one end to the other effortlessly which makes implementing analytics easy. Node.js has the capability to handle large amounts of data at one time. To overcome the problem of dealing with larger data, it is important to have a mechanism for breaking the large data into multiple chunks. Using backpressure, which comes from implementing Node.js, you can use a computer's resources while processing very large sets of data.

Use Case 3: Wireless Connectivity

The Problem:

Bi-directional signal connectivity between IoT devices is a key challenge.

The Solution:

Node.js server ensures data connectivity without any request blockage

Node.js is one of the most effective solutions to create a proxy server for data connectivity and routing as it supports I/O connectivity without blocking. Some JavaScript libraries for Node.js such as Node-Red, NodeMcu, and Node Serialport offer ready-made solutions for connecting IoT devices.

Use Case 4: Realtime Data

The Problem:

Scalability bottlenecks in real-time data is very common

The Solution:

Node.js makes real-time data a boon for web apps

Node.js is a good fit for building real-time web apps by using push technology over web sockets (a two-way communication between the servers and clients). What's more revolutionary about Node.js is that it is the best choice for creating server-side web apps.

Use Case 5: Queued I/O Inputs
