1 – Make something that uses only one sensor on Arduino and makes the ellipse in p5 move on the horizontal axis, in the middle of the screen, and nothing on arduino is controlled by p5
Code:
const int potPin = A0; void setup() { Serial.begin(9600); } void loop() { int potValue = analogRead(potPin); // send the potentiometer value to the serial port Serial.println(potValue); delay(50); }
2 – Make something that controls the LED brightness from p5
Code:
int ledPin = 6; void setup() { Serial.begin(9600); pinMode(ledPin, OUTPUT); } void loop() { while (Serial.available() > 0) { // read the incoming brightness value from p5.js int brightness = Serial.parseInt(); // adjust the LED brightness based on the received value analogWrite(ledPin, brightness); } }
3 – Take the gravity wind example and make it so every time the ball bounces one led lights up and then turns off, and you can control the wind from one analog sensor
int potPin = A0; int ledPin = 6; void setup() { Serial.begin(9600); pinMode(LED_BUILTIN, OUTPUT); pinMode(potPin, INPUT); pinMode(ledPin, OUTPUT); } void loop() { digitalWrite(LED_BUILTIN, LOW); while (Serial.available()) { digitalWrite(LED_BUILTIN, HIGH); int ambientBrightness = Serial.parseInt(); if (Serial.read() == '\n') { int sensorReading = analogRead(potPin); Serial.println(sensorReading); } if (ambientBrightness >= 350 && ambientBrightness <= 360) { digitalWrite(ledPin, HIGH); } else { digitalWrite(ledPin, LOW); } } int sensorReading = analogRead(potPin); Serial.println(sensorReading); }
