I need to create a precise speedometer for a bicycle. The idea is to mount several magnets for a Schmidt trigger on the rear hub. I need to know could a ATtiny45 be capable of measuring this speed and sending PWM signal result to an Arduino Duemillanove at the same time? One of my friends said it m…

Can ATtiny45 be used for this application?

And you go from Hall sensor to driving a meaningful display how?
