Arduino for Beginners - 2022 Complete Course - Debounce the Push Button

The video tutorial explains how to implement a debounce mechanism for a button to avoid multiple detections when the button is pressed or released. It covers setting up global variables for time tracking, implementing loop logic to check button state changes, and updating variables accordingly. The tutorial also discusses testing and adjusting the debounce delay for optimal performance and explores alternative approaches to achieve the same functionality without using delays.
