Hi all,
I have put together my microcontroller with LCD display, L298 H-bridge to rum
motor with PWM signal, everthing works fine. I want to display the digital
value of the motors actual speed. I have an opto-interrupter with optical
wheel on the motor. I want to take the pulses from the motor to be displayed
as the speed, I have an ADC input & a timer input. Which would be a better
input & what steps do I need to follow to make the converson to produce the
actual 4 digit display? Or maybe can you suggest a book with this information.
I know how to make the display work so that`s no problem.

Thanks Bill
