microcontrol ignition circuit
hi all, i'd like to find out more about this and would appreciate any help. the ignition (rpm) signal is at 12v and is a square wave signal.
what would be the best way to interface this signal to a microcontroller? do i have to use a comparator or adc or some other way?
thanks for any help.
