Arduino Experiment 3 - RGB Modify

Definition : We change RGB Led's colour by using potentiometer. Changing resistor values gives different colours.

Arduino Code

/*

  Blink

  Turns on an LED on for one second, then off for one second, repeatedly.

  This example code is in the public domain.

 */

// Pin 13 has an LED connected on most Arduino boards.

// give it a name:

int led = 7;

int led2 = 6;

int led3 = 5;

// the setup routine runs once when you press reset:

void setup() {               

  // initialize the digital pin as an output.

  pinMode(led, OUTPUT);

  pinMode(led2, OUTPUT);

  pinMode(led3, OUTPUT);  

}

// the loop routine runs over and over again forever:

void loop() {

  digitalWrite(led, HIGH);   // turn the LED on (HIGH is the voltage level)

  digitalWrite(led2, HIGH);

  digitalWrite(led3, HIGH);

}
