I want to make a digital speedometer. Concept is to measure the rpm of the wheel for say 5 sec. the revolutions will be counted by a counter. After every 5 sec the count is latched and the counter is reset. the latched count is fed to an EPROM which has the speed data fed in depending upon the wheel diameter. the output is the corresponding speed which is diplayed on 7 segment LED. Now my problem is HOW TO GENERATE THE PULSES FOR RUNNING THE COUNTER? need help on this please
