Contact less IR tachometer using PIC16F628A

Tachometer is a device that gives the information about the rotational speed of any shaft or disc. It usually measures the speed in revolutions per minute (RPM). 
I want it to measure the speed of motor so for this i searched the net and found various design but unfortunately they don't worked for me, don't know why?. So i decided to make my own tachometer using PIC16F628A micro-controller and LCD.
