Microbit LED Strip

Program a strip of LEDs to light up and show colourful displays!

1 - Introduction

In this project we are going to program a strip of 30 LEDs to light up different ways. We will connect our Microbits to them and use the microbits to send the instructions to the LED strip!

2 - Create a new Microbit project

To get started create a new Microbit project.

3 - Add the neopixel extension

To access the blocks we need to program the LED strip, you need to add the neopixel extension to your project.

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!
