Three potentiometers control Red, Green and Blue colors of an RGB LED with Arduino Uno board.

In this beginner project you'll learn how to build a system which alows an LED to change to the color you want just by tweaking 3 knobs.


We are going to be using three PWM pins (9, 10, 11) from the Arduino Uno board to fade each individual color from the RGB LED with three potentiometers each connected to an analog pin (A0, A1, A2). In addition to that we'll be able to read each and every value of the colors in the Arduino IDE Serial Monitor. Follow the code, it's very straight forward.
