This project turns the tiny Puck.js into a wireless (BLE) MIDI controller.
The sketch in this project programs the Puck.js button to send a MIDI CC message. Any music app or music notation app with MIDI Learn capabilities can be controlled using this message. Currently, I'm using a Puck.js to advance pages in forScore.
Connect your Puck.js to the Espruino IDE, upload the provided sketch, and then follow the MIDI Learn instructions in your chosen music app.
