In this guide we’ll build on the techniques learned in Part 1 of the series while we explore several types of Arduino interrupts and show how they can be used to help your Arduino juggle even more tasks while keeping your code simple and responsive.
We'll learn how to harness the timer interrupts to keep everything running like clockwork. And we'll explore using external interrupts to give us notifications of external events.
