Arduino Interrupts and Debouncing
Interrupts are an extremely useful, yet often feared element of microprocessors. Interrupts allow you to run a program, while still being able to react to asynchronous input from the outside world.
On many platforms they can be confusing to implement, but the arduino makes it easy! In this week’s episode, I’ll show you how to use a hardware-debounced button to activate a hardware interrupt on the arduino.
I’d suggest you go check out episode 2, where I initially introduced button debouncing, if you haven’t already. I won’t be covering timer interrupts in this episode, since I recently wrote an extensive blog post about using them. Enjoy the video!
