In this tutorial, we will create a sketch in which the RGB LED emits only the green light that turns on and off gradually. In the second example, you will see that red, green and blue lights also turn on and off gradually.
This project is suitable for school students and beginners.
For this experiment, you will need 1 RGB LED and three 220 Ohm resistors.
|U1||1||Arduino Uno R3|
|3||220 Ω Resistor|
Experiment 1: Only Green light turns on and off gradually
