This experiment will make a simple passive infrared anti-theft alarm. The alarm consists of an infrared transmitter, receiver, buzzer and LED indicator. Under normal circumstances, the green LED flashes constantly, indicating that the monitored area is normal. Once someone breaks into the monitored area, the green LED goes out, the red LED flashes quickly, and the buzzer sounds an alarm immediately.
