Ok, so I built up the IR Sensor kit from Jay Car. It worked for about 20mins then decided to die on me after I had just got it working with Maxuino.


So I tried an IR sensor light from Bunnings. This ended up only working at the distance of about 20cm, the box said 20feet.
Decided I would buy a wireless infra red sensor door chime/alarm. Took it apart and wired it up, and it decided that it would die on me.

My conscience was trying to tell me something I think, IR would not work for this project no matter what I did. I'm going to keep trying these things out because I really want to use a sightless beam to track people and make the project as subtle as possible.
