A laser harp is an electronic instrument that lets you “pluck” laser beams like a harp to play notes. In this guide, you’ll learn how to build your own version of a laser harp using a Feather M4 Express or Feather RP2040, a Music Maker FeatherWing and code written in CircuitPython. VL53L4CD time of flight sensors are used to detect when you’re playing a note instead of simply detecting the break-beam. This means we can do cool stuff like use the distance data from the time of flight sensors to convert into different MIDI values such as modulation, sustain and velocity.
This project will show you how to use the Music Maker FeatherWing as a MIDI synth and use the time of flight sensors to control different MIDI parameters.
