Abstract
This chapter takes a look at the Analog Comparator’s single interrupt. I think this is my favorite feature of the ATmega328P, and I will use it later on in this book when I give an example of a real-world application using interrupts. I have yet to see any articles or projects which make use of this interesting feature.

Notes
- 1.
On the ATmega328P in its 28 pin dual in line package, it is pins A0 through A5. If your Arduino board has a surface mount ATmega328AU package, then you can also use Arduino pins A6 and A7 – if those are connected to a header somewhere on the board. Some Uno clones, mine included, have this feature.
- 2.
Yes, that’s what we do; we have to disable the Analog Comparator’s disable bit!
- 3.
This is something that authors normally say when something is either too difficult, too simple, or they just can’t be bothered. None of this is the case here of course!
