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.

What is the purpose of the debounce delay in button state management?

Explain how the last time the button state changed is recorded.

Describe the process that occurs when the button is pressed and released.

What happens if the debounce delay is set to zero?

How can you determine the appropriate debounce delay value for a circuit?

Discuss the implications of setting a debounce delay that is too high.

What is the significance of updating the last time button changed after the state has changed?
