Tachometer for car on PIC16F84A

Tachometer for a car with the no contact system of ignition on PIC16F84A

Principle of work: It is based on measuring of time of 50 impulses from the sensor of ignition distributor (Hall generator) . The count is farther done in rotation/minute and a data outputs by a 4-bit line on MT-16SD. Also a clock and minutes of work of engine bring out to socket.

Exactness of tachometer: at 3000 rot/min + -0,75 rot/min, at 1000 +-0,1 rot/min.
