need IR transmitter / receiver projects ..


I need a project using IR transmitter / receiver interface with pc
that whenever there is a cut or an object disturbing the transmission between these transmitter and receiver sensors, PC should show message according to the situation of these sensors

and that will happen using the parallel port

 if anyone have tried something like this or if you know a site have projects about it
please help me, I've never done projects using the parallel port  

Simple stuff. Easiest way is to use Linux

do you know where can I find the circuit and the software controller ?

I found something about IR sensor to count the visitors
do you think that it's possible to change it to be as home security system !
If you have a counter, all you need to do is check when thecounter increments when it should not do - that's the alarm condition.
