auto tracking

Hello. I'm totally new to arduino and have just got my first board. Can anyone help me...I'm trying to use it to control a servo that can track a moving object ( it doesn't have to be to accurate). I was going to use PIR sensors and get them to trigger the movement..... Any ideas? Cheers.
