I’ve put up the schematic and code for the little midi keyboard I made…

Awesome schematic

I’m pretty sure most resistor values would work alright in place of the 10Ks, but if I’m wrong, then… tough. They’re just acting as pulldown resistors anyway. The value for the resistors marked with a question mark depends on the current required by your LEDs.

Code

Here is the code which needs to go on your Arduino board, and also the code for the Processing app which converts the serial data to midi. The Processing app requires the rwmidi library, which you can get here.
