3.MultiPurposeButton

This examples shows how to use the MultiPurposeButton class to detect different kinds of push button events.

Boards:

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

Connections

• 2: Momentary push button (other pin to ground)

The internal pull-up resistor will be enabled.

Behavior

• Short presses, long presses, multiple presses, etc. are printed to the Serial monitor.
