    I would like to make a speed display circuit. it would measure amount of pulses say in 10 seconds and it would display it on a seven segment display. i would like to implement it using a pic. how should i proceed?

    You will need to learn how to program the PIC. You will need enough electronic knowledge to present the PIC with pulses it can take in. You will need to understand what it takes to drive a 7 segment display.

    It's a good starting project for getting familiar with a PIC. There are easier ways to make a tachometer or speedometer.

    or use shaft encoder as input to the PIC. then process the pulsses to take the speed.
