This project will show you how to make a light-controlled sound machine, running you through some of the capabilities of the new micro:bit to create a standalone experimental, electronic instrument with LED visualisation. Although it can run from the micro:bit’s built-in speaker, it’s sonic power becomes apparent when connected to an amplifier and speaker.
Here is an overview of what you’ll be assembling. Below you’ll see a broken-down guide.
You should now have the instrument ready.
Above you can see the controls for your light instrument. Using a combination of button presses, tilting and light exposure you can change and modulate the sound to your liking. The LED matrix will graphically reflect what the sound is doing.
The first thing you might want to do is play your instrument through a HiFi or speakers to appreciate its sound range.
Ensure to have the volume on your speakers set to low. The micro:bit IS LOUD!
