RotaryEncoder

This example demonstrates the use of relative MIDI CC rotary encoders that can be used for changing effect parameters, volumes, pan and balance controls, etc.

Boards: 🛈
AVR, AVR USB, Nano Every, Due, Nano 33 IoT, Nano 33 BLE, UNO R4, Pi Pico, Teensy 3.x, ESP32, ESP8266, ESP8266

Connections

Connect the common terminal of the encoder to ground. The built-in pullup resistors will be enabled.

Behavior

Mapping

Select the Arduino as a custom MIDI controller in your DAW, and use the relative CC mode.
There are three main modes for sending relative messages, make sure you use the same one in this sketch as in your DAW.
