MIDI Control Surface library for Arduino
Control-Change-Potentiometer.ino

Control-Change-Potentiometer

This example demonstrates the use of MIDI Control Change potentiometers that can be used for changing effect parameters, volumes, pan and balance controls, etc. It can control almost any knob in your DAW software.

Boards:
AVR, AVR USB, Nano Every, Due, Nano 33, Teensy 3.x, ESP32

Connections

Connect the left terminal of the potentiometer to ground, and the right one to VCC.

Behavior

Mapping

Select the Arduino as a custom MIDI controller in your DAW, and use the MIDI learn option to assign the potentiometer to a function.
It will send the MIDI Control Change Channel Volume parameter for channel 1.
