What does it do?
This isn't really a project I set out to build-it's just an intermediate phase in the development of Serv-O. I took the "brain" I made for him:
...and slapped it on my Magician Chasis with a 7.2v RC battery. The Mega is actually a 328, despite what the sticker I made says. The other two chips are a 74HC14 and an SN754410, with a 7805 limiting the voltage.
