Step 2: Components

  • RGB Leds
  • Jumper Wires
  • Breadboard
  • Arduino Uno
  • USB Cable for Arduino

Step 3: Led Mount on Breadboard

Connect cathod pins to Gnd

and

andode pins to arduino pins 3 to 12

Step 4: Wire Connection

Step 5: Code

RGB Led Chaser Code

Here is the code

int ledpin;

int pot = A0;
void setup() {
for(ledpin=2;ledpin<=8;ledpin++){
  pinMode(ledpin,OUTPUT);
 }
}
void loop() {
  for(ledpin=2;ledpin<=8;ledpin++){
  int value = analogRead(pot);
  digitalWrite(ledpin,HIGH);
  delay(value);
  }
    for(ledpin=2;ledpin<=8;ledpin++){
      int value = analogRead(pot);
  digitalWrite(ledpin,LOW);
  delay(value);
  }
}
