Debouncing button or switch inputs on microcontrollers can be a challenging problem for those first starting to program these devices. Part of the reason for this difficulty is that real-world buttons ...

This library introduces the MyButton class, which makes it easy to process push-button input by Arduino/ESP32. Connect the push-button between a GPIO-pin and GND (see the diagrams below). Prefer pins ...

This project demonstrates how to interface a push button with an Arduino Uno using External interrupt INTO, and sequentially control three LEDs using register-level programming. When the button is ...
