RGB LED for micro:bit

The MonkMakes RGB LED for micro:bit provides a colourful add-on to your micro:bit. Connect it up with alligator clips and then use the three outputs of your micro:bit to control the red, green and blue channels to mix up any colour of light you want.

Features

• Easy to connect
• Powered directly from micro:bit pins
• Useful for teaching color mixing.
