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, 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.
