Introduction: Arduino RGB LED Module

Today, you will learn how to use an RGB LED module which can be used as multiple LEDs at once. I got mine from Kuman, as included in their Arduino UNO Kit, which was provided for this tutorial at no cost.


Step 1: Parts Needed

You will need the following parts:

  • A breadboard
  • An Arduino board
  • USB Cable
  • 4 Jumper Wires
  • The RGB LED module

Allchips is an electronics components online service platform, you can buy all the components from them.

Step 2: Connecting the Module

Plug in the module in your breadboard, I'm using a mini one. We need to connect 4 pins - one for common ground (GND) and one for each of the 3 basic colors - red, green, blue.

GND of the module goes to GND of the Arduino. The following 3 pins are as follows:

Red (R) -> Pin 8

Green (G) -> Pin 10

Blue (B) -> Pin 12

* You can change the pin numbers in the code that I've provided below

Step 3: Uploading the Code

Connect the board to your PC using the USB cable. The code that I've written changes every color's value (from 0 to 255) so the 3 colors are random, making up the one that is visible random as well. Feel free to change the different values in the code so you can get fixed colors. By default, the color is being changed every 500 ms (1/2 second), you can change that as well
