The modern line up of ATtiny micro controllers is pretty sweet. They go for under a dollar a piece on digikey (best place to get them). They are mostly surface mount so an ebay smd adapter board kit makes them easy to use. I picked the attiny1604 but there are many variations. This is the arduino core for them and if you scroll down has all the info and variation comparison. https://github.com/SpenceKonde/megaTinyCore
