ArduinoBoy it’s a Gameboy-MIDI bridge based on Trash80 Arduino Boy.

With this device you can play the Gameboy just like a piano,
I personally use it with Ableton Live in my music making workflow.

As it was one of my first projects, I made the circuit by hand on a Vero board without proper tools, so the final result looks a little bit ugly.

As the first attempt was kinda ugly, I made a generic PCB schematic with a software called EasyEDA (see image below).

This schematic it’s still not tested, but it should work properly.
Feel free to message me if you find any errors in it.
