RGB LED for micro:bit
MNK00064
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.

TRAFFIC SIGNAL EXAMPLE
Paste the following code into the Python window and then Download the file and copy
it onto your your micro:bit
from microbit import *
def set_rgb(red, green, blue):
pin0.write_analog(red)
pin1.write_analog(green)
pin2.write_analog(blue)
while True:
set_rgb(255, 0, 0)
sleep(4000)
set_rgb(800, 100, 0)
sleep(1000)
set_rgb(0, 1023, 0)
