Difficulty: Level 3

Time to Complete: Approximately 40 min

Challenge Description: Make the RGB LED to change colours when twisting the potentiometer.

Answer:

Code

const int red= 9;
const int green= 10;
const int blue= 11;
const int pot= A0;

const int distime= 100;

void setup()
{
  pinMode(pot, INPUT);
}

void loop()
{
  int a=analogRead(pot)/63.75;
  if (a==4)
  {
    analogWrite(green,255);
    delay(distime);
    analogWrite(green,0);
  }
  else if (a==3)
  {
    analogWrite(blue, 255);
    delay(distime);
    analogWrite(blue,0);
  }
  else
  {
    analogWrite (red,255);
    delay(distime);
    analogWrite(red,0);
  }

}
