Microbit LED Strip

In this step-by-step lesson, you'll learn to program a 30-LED strip using Microbits. You'll create a new Microbit project, add the neopixel extension, and set up the LED strip. You'll then program the LEDs to light up in different colours and patterns, including a rotating rainbow effect. Explore the Neopixel toolbox and experiment with your own lighting designs.
