Laser Barrier Detector

This is some what different circuit.But this is so simple circuit.Some times some people have used some security systems by using lasers you can use this one for detect those beams.what you have to do is attaching more than 10 LDR for a stick when you walk send it before you.Then it will detect those barriers.
