How to Make One Button Have the Functionality of Two or More with Arduino

This tutorial teaches how to use an Arduino to make a single button perform multiple functions. It covers the materials needed, circuit setup, and code explanation. The tutorial demonstrates how to track button press duration to trigger different LED lights, using a while loop and if-else statements. It concludes with a demonstration of the code in action.
