This tutorial introduces how to integrate a push button into your Arduino projects to control an LED. Using a digital input pin, youll learn to read the state of the button and use its status to turn an LED on and off. This project builds on our previous tutorial by adding a push button and demonstrating how to set up and code for interactive elements. Through the demonstration, youll understand how to handle button states and debouncing, enhancing the interactive capabilities of your Arduino projects.
