AC doesn't necessarily mean 110-240V mains voltages, it just mean alternating current. It could be 12V from a transformer or some other induction coil like RFI

- dotancohen 4y agoSure, but is that ever actually encountered in practice?
- ChuckNorris89 4y agoIn hobby/student projects, yes, very often. Maybe even in some cheap white goods. Otherwise they wouldn't have bothered publishing application notes on it. It's awesome to just hook up a random coil you found/wound to the pins of an AVR and watch it just work.
- dotancohen 4y agoTerrific, thank you! I've never seen this, but it's good to know if I ever come across such a device.
