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.

Getting Started

Connecting to your micro:bit

Connect the RGB LED to the micro:bit as shown below. When attaching the alligator clips to the micro:bit, make sure that the clips are perpendicular to the board so that they are not touching any of the neighbouring connectors on the micro:bit edge connector.

pin1.write_analog(green)
pin2.write_analog(blue)

while True:
set_rgb(255, 0, 0)
