To get started create a new Microbit 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:
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.
We're going to use the microphone in the microbit to detect when there's a loud sound. When it detects a loud sound we will light up the first LED on the strip white.
We put the strip show block inside the forever block so that the strip is constantly being updated, this will be important later.
Add the following code to your project.
Download the code onto your microbit and connect your LED strip to it using the crocodile clips.
Test that it works by clapping your hands near the microbit, the first LED should light up white.
Give your project a name and send it to your Microbit by following these steps:
