Assignment #12 – Stefania Petre (with Amal and Afra)

Initial connection and wiring from the schematic:

Exercise 1:

This was probably the easiest exercise, we just had to edit the code that was in the Week 12 Lecture Notes.

P5.js Code:

let potentiometer = 0;

function setup() {
  createCanvas(640, 480);
  textSize(18);
}

function draw() {
  background(255);
 
  if (!serialActive) {
    text("Press Space Bar to select Serial Port", 20, 30);
  } else {
    text("Connected", 20, 30);
    text('Potentiometer = ' + potentiometer, 20, 70);
  }

 
  let ellipseX = map(potentiometer, 0, 1023, 0, width);
  fill(0);
  ellipse(ellipseX, height / 2, 50, 50);

function keyPressed() {
  if (key === ' ') {
    setUpSerial();
  }
}

function readSerial(data) {
  if (data != null) {
    let trimmedData = trim(data);
    if (!isNaN(trimmedData)) {
      potentiometer = int(trimmedData);
    }
  }
}

Arduino Code:

void setup() {
  Serial.begin(9600);

  pinMode(LED_BUILTIN, OUTPUT);
  digitalWrite(LED_BUILTIN, HIGH);
  delay(200);
  digitalWrite(LED_BUILTIN, LOW);
}

void loop() {
  int sensorValue = analogRead(A1);

  Serial.println(sensorValue);

  delay(10);
}
