PB202 MIDI to CV
That MIDI and MIDI over USB board give two 0 to 5V output signals, CV1 and CV2.
The CCNumber are 1 and 2 on chanel 1. That can be easily modified in the code.
For uploading code on the Arduino the Midi In jumper has to be off. One has to set the jumper for getting Midi in on the Arduino.
The funktion of the potentiometer is not implemented in the code yet!
