How to Control Color of RGB LED with Micro:bit?

Overview
 

In this project, we will use a keyestudio RGB LED module. This Common Anode RGB LED module is a fun and easy way to add some color to your projects. In our program, we will connect the RGB module to micro:bit, then control the P0, P1, P2 Analog Input of micro:bit main board. You will learn how to control the RGB LED on the module firstly show three colors (Red, Green and Blue), then quickly change the color state.

Component Required:
 

• Micro:bit main board*1

• Keyestudio Micro bit Sensor V2 Shield*1

• USB Cable*1

• keyestudio RGB LED Module*1

• DuPont jumper wire*4

• Premium Battery Holder 6-cell AA*1

• 1.5V AA Battery*6

RGB LED Module:
 

RGB comes from the initials of three additive primary colors, red, green, and blue. RGB LEDs are like 3 regular LEDs in one, how to use and connect them is not much different. They come mostly in 2 versions: Common Anode or Common Cathode. Common Anode uses 5V on the common pin, while Common Cathode connects to ground.

This keyestudio RGB LED module is Common Anode. It can be seen as separate LEDs. LEDs have three different color-emitting diodes that can combined to create all sorts of colors. This RGB LED module is very easy for wiring, with a fixed hole that you can mount it on your any devices.

Test Results
 

Done wiring and powered up, send the code to micro:bit, you should see the RGB module firstly show three colors, separately red, green and blue light. Then change the color quickly and circularly.
