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!
To get started create a new Microbit project.
Go to the Makecode.com Microbit website using the link below and click on the 'New Project' button underneath the 'My Projects' heading.
https://makecode.microbit.org/
Install the micro:bit app on your iPad or tablet.
Open the app, tap 'Create code' and then create a new project.
To access the blocks we need to program the LED strip, you need to add the neopixel extension to your project.
To add an extension follow these steps:
- Click on 'Advanced' in the toolbox
- Click 'Extensions'
- Type the name of the extension in the search box
- Click on the extension in the search results
- The extension and all it's blocks will be added to your toolbox
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.
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!
