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 ...

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 project demonstrates an interrupt-based embedded system built using the Arduino Nano 33 IoT, a BH1750 light sensor, and a slide switch. The built-in LED is controlled through external ...
