you can look at my instructable " Laser Sensor Timer " The second sensor's circuit latches itself. Instead of it going to the stopwatch, it can turn on a siren circuit to make the siren go off. I'll make a instructable about that when I have time. Hope this helps! Send me some thing if you still don't understand.
