Salam Mani Bhai, i suggest you use http://www.8051projects.net for issues regarding microcontrollers as this is more concerned with analog electronics etc..... and the other thing is that i've seen people use ultrasonic transcievers for distance finding.... the technique followed is that when the transmitter transmits waves a timer is started, when the reciever receives the waves and the timer stops and the time is calculated and so distance is calculated as we know that the ultrasonic waves have a constant speed.... anyways doing it through IR will be interesting but i wonder if its achievable or not.....
