16 key USB MIDI using Arduino Pro Micro
thingiverse
I was bored a bit so I made myself 3D Printed 16 key USB MIDI using Arduino Pro Micro. I used Arduino Pro Micro, TTP229 16 Key Capacitive Keypad and one WS2812 LED. I designed casing using Adobe 123Design. All together was just around 5$. Pro Micro is great because it can act as USB HID device and it support native MIDI over USB, so you don't need any cables/adapters for using it with your favorite software. For now, this device does nothing special, it just sends out MIDI data for 12keys. "noteOn(0, 47+key-4+octave, 110);" Two buttons I coded so they change octave. This way you can use it as an instrument. At the end of the video, I mapped one button to stop playing all. But you can do whatever you want you just need an idea, I am thinking about extending it to be generic keyboard and send data to my IoT system running Node-Red. Sorry for crappy video, I don't have the right equipment and just two hands. I just wanted to show you how simple is to make cheap MIDI device :) Source is avaliable on my GitHub https://github.com/P3Hi/3D-Printed-16-key-USB-MIDI-using-Arduino-Pro-Micro More about project is posted on Hackster.IO https://www.hackster.io/p3hi/3d-printed-16-key-usb-midi-using-arduino-pro-micro-c6c23e
