I made my own Stylophone - and you can too

The StyloDuino is a custom arduino UNO based digital synthesizer inspired by the Stylophone S-1.

For this project I made a custom PCB with JLCPCB and components from Digikey. Soldered the board together, and wrote some basic code to interpret the keys and convert each key to a musical note.
