RGB module has 4 pin R,G,B,GND( standing for Red,Green,Blue and Ground). When R,G,B pins get different values of PWM signal, its LED will show different colors. In this project, we will use Arduino UNO R3 to feed different value to RGB module and output different colors.
Parts and Devices:
Arduino UNO R3 x 1
USB cable x 1
Breadboard x 1
RGB module x 1
Please download sample code from http://osoyoo.com/wp-content/uploads/2016/07/RGB.ino, unzip the file and load it into Arduino IDE.
After running the code, the LED in RGB module will constantly change colors.
