Hi everyone!
I have to do a digital tachometer .
Informations :
- speed range : 300-600 rot/min ;
- measuring time : 0,2 seconds ;
- display resolution : 10*rot/min;
- optical warning when overruning from 550 rot/min .
My teacher said that i should generate a signal with two timers on a pin and then to convert it into rotations per minute . After that i should display it on 7segments or LCD display .
I will be very grateful if you will help me with this project ! Thanks !
