Arduino for Beginners - 2022 Complete Course - Software Debounce Inside an Interrupt

The video tutorial explains the comparison between interrupt and debounce code, focusing on setting up variables for button release and implementing debounce logic using time checks. It highlights the importance of using the volatile keyword for variable modification within interrupts. The tutorial also discusses compiling the code and checking its functionality. Finally, it addresses the limitations of software debounce and suggests hardware solutions for better performance.

What are the two variables that need to be created for handling button release?

Explain the purpose of the debounce delay in the context of button interrupts.

Describe the difference between handling button state in a loop versus using an interrupt.

What is the significance of using 'volatile' for certain variables in the interrupt context?

Why is it advised to be cautious when using 'Millis' inside an interrupt?

What is the recommended solution for hardware debounce, and why is it preferred?

What are the potential issues with using low-quality push buttons in projects?
