For this assignment, I collaborated with Shahd. We based our project on the example codes and made changes as we see appropriate. Shahd did the second exercise and I did the first exercise. We worked together to complete the third exercise.

Exercise 1:
p5 sketch:
int leftLedPin = 7;
int rightLedPin = 4;
void setup() {
// Start serial communication so we can send data
// over the USB connection to our p5js sketch
Serial.begin(9600);
// We'll use the builtin LED as a status output.
// We can't use the serial monitor since the serial connection is
// used to communicate to p5js and only one application on the computer
// can use a serial port at once.
pinMode(LED_BUILTIN, OUTPUT);
// Outputs on these pins
pinMode(leftLedPin, OUTPUT);
pinMode(rightLedPin, OUTPUT);
// Blink them so we can check the wiring
digitalWrite(leftLedPin, HIGH);
digitalWrite(rightLedPin, HIGH);
delay(200);
digitalWrite(leftLedPin, LOW);
digitalWrite(rightLedPin, LOW);
// start the handshake
while (Serial.available() <= 0) {
digitalWrite(LED_BUILTIN, HIGH); // on/blink while waiting for serial data
Serial.println("0,0"); // send a starting message
delay(300); // wait 1/3 second
digitalWrite(LED_BUILTIN, LOW);
delay(50);
}
}
void loop() {
// wait for data from p5 before doing something
while (Serial.available()) {
digitalWrite(LED_BUILTIN, HIGH); // led on while receiving data
if (Serial.read() == '\n') {
int sensor = analogRead(A1); //potentiometer
Serial.println(sensor);
}
}
digitalWrite(LED_BUILTIN, LOW);
}
Exercise 2:
int leftLedPin = 6;
void setup() {
// Start serial communication so we can send data
// over the USB connection to our p5js sketch
Serial.begin(9600);
// We'll use the builtin LED as a status output.
// We can't use the serial monitor since the serial connection is
// used to communicate to p5js and only one application on the computer
// can use a serial port at once.
pinMode(LED_BUILTIN, OUTPUT);
// Outputs on these pins
pinMode(leftLedPin, OUTPUT);
// start the handshake
while (Serial.available() <= 0) {
digitalWrite(LED_BUILTIN, HIGH); // on/blink while waiting for serial data
Serial.println("0,0"); // send a starting message
delay(200); // wait 1/3 second
digitalWrite(LED_BUILTIN, LOW);
delay(200);
}
}
void loop() {
// wait for data from p5 before doing something
while (Serial.available()) {
digitalWrite(LED_BUILTIN, HIGH); // led on while receiving data
int brightness = Serial.parseInt();
analogWrite(leftLedPin, brightness);
if (Serial.read() == '\n') {
Serial.println("0,0");
}
}
digitalWrite(LED_BUILTIN, LOW);
}
Exercise 3:
int leftLedPin = 7;
int rightLedPin = 4;
void setup() {
// Start serial communication so we can send data
// over the USB connection to our p5js sketch
Serial.begin(9600);
// We'll use the builtin LED as a status output.
// We can't use the serial monitor since the serial connection is
// used to communicate to p5js and only one application on the computer
// can use a serial port at once.
pinMode(LED_BUILTIN, OUTPUT);
// Outputs on these pins
pinMode(leftLedPin, OUTPUT);
pinMode(rightLedPin, OUTPUT);
// Blink them so we can check the wiring
digitalWrite(leftLedPin, HIGH);
digitalWrite(rightLedPin, HIGH);
delay(200);
digitalWrite(leftLedPin, LOW);
digitalWrite(rightLedPin, LOW);
// start the handshake
while (Serial.available() <= 0) {
digitalWrite(LED_BUILTIN, HIGH); // on/blink while waiting for serial data
Serial.println("0,0"); // send a starting message
delay(300); // wait 1/3 second
digitalWrite(LED_BUILTIN, LOW);
delay(50);
}
}
void loop() {
// wait for data from p5 before doing something
while (Serial.available()) {
digitalWrite(LED_BUILTIN, HIGH); // led on while receiving data
int LED_STATE = Serial.parseInt();
//int right = Serial.parseInt();
if (Serial.read() == '\n') {
digitalWrite(rightLedPin, LED_STATE);
int sensor2 = analogRead(A1);
delay(5);
Serial.print(sensor2);
Serial.print(',');
Serial.println('Y');
}
}
digitalWrite(LED_BUILTIN, LOW);
}
