CountPressedButtons
Example of using the standard library algorithms and the Button class.
- Boards:
- AVR, AVR USB, Nano Every, Nano 33 IoT, Nano 33 BLE, UNO R4, Pi Pico, Due, Teensy 3.x, ESP8266, ESP32
This sketch reads a number of push buttons or switches, and uses the standard library algorithms to count how many of them are pressed.
The internal pull-up resistors are enabled and the switches are debounced.
