Cole 3 Potentiometer Fade
I did the option with 3 pots, each controlling the brightness of an LED. The code is below.
int potPini = 2; // select the input pin for the potentiometer
int ledPini = 9; // select the pin for the LED
int potPinj = 1; // select the input pin for the potentiometer
int ledPinj = 10; // select the pin for the LED
int potPink = 0; // select the input pin for the potentiometer
int ledPink = 11; // select the pin for the LED
int vali = 0; // variable to store the value coming from the sensor
int valj = 0; //variable to store the value coming from the sensor
int valk = 0; //variable to store the value coming from the sensor
void setup() {
Serial.begin(9600);
}
void loop() {
vali = analogRead(potPini); // read the value from the sensor, between 0 - 1024
valj = analogRead(potPinj); // read the value from the sensor, between 0 - 1024
valk = analogRead(potPink); // read the value from the sensor, between 0 - 1024
Serial.println(vali);
Serial.println(valj);
Serial.println(valk);
analogWrite(ledPini, vali/4); // analogWrite can be between 0-255
analogWrite(ledPinj, valj/4); // analogWrite can be between 0-255
analogWrite(ledPink, valk/4); // analogWrite can be between 0-255
}
