The RGB LED can emit different colors by mixing the 3 basic colors red, green and blue. So, it actually consists of 3 separate red, green and blue LEDs, packaged in one box. This is why it has 4 leads, one for each of the 3 colors and a common cathode or anode depending on the type of RGB LED. In this tutorial I will use a common cathode. Components required for this Project : RGB Led - Buy Arduino Uno - Buy Breadboard and Jumpers - Buy Circuit Diagram Above is the circuit diagram of the RGB Led and Arduino Uno , As you can see the ground pin  of the RGB LED is connected to the ground of the Arduino and other 3 pins of RGB Led are connected to the PWM Pins of Arduino Uno (9, 10, 11). Code int ledPin = 9;  int ledPin1 = 10; int ledPin2 = 11; void setup() {} void loop() {   for (int fadeValue = 0 ; fadeValue <= 255; fadeValue += 5)    {     analogWrite(ledPin, fadeValue);     delay(20);   }   for...
