Hi,
I want to design a circuit for measuring a speed of an object .
My approach is to use two IR sensors and the distance between them is fixed .
once the object passes the first sensor the time starts counting and when it passes the second sensor the time stops counting, the speed measured by speed=distance/time.
I can make this circuit using microcontroller easily but i need to build the circuit without using microcontrolles ?
Any help ?
thanks in advanced
