Serial-Interface

This example demonstrates how to use a Serial MIDI Interface, for use with 5-pin DIN connectors, for example.

Boards:

AVR, AVR USB, Due, Nano 33, Teensy 3.x, ESP32

Connections

• 5: momentary push button (to ground)

The internal pull-up resistor for the button will be enabled automatically.

Behavior

• This is just a simple MIDI controller with a single note button and an LED.

Mapping

None.
