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.

Warning: Your screen size is quite small for viewing this. Rotate your device into landscape mode if you can.

4 - Setup the LED Strip

To be able to interact and program the LED strip we will need a variable that stores the strip.

Add the following code to your project. We set the value to be 30 as there are 30 LEDs on the strip.

5 - Make it red

Now let's program the A button on your microbit to turn all the LEDs red.

Add the following new code to your project.

Download your updated code to your microbit and press the A button, the LED strip should light up all red!
