This project shows an Arduino-powered laser light security system with an alarm. The device uses the laser beams to identify any trespassing into a certain area. The alarm system is managed by the Arduino microcontroller. Two laser modules, two photoresistors, a buzzer, and an Arduino board make up the system. The two opposing edges of the space that needs to be secured are where the laser modules are situated. Between the laser modules, the photoresistors are positioned, and they are used to detect any breaks in the laser beam. The photoresistor notices an interruption in the laser beam and alerts the Arduino board when it happens. To notify the user of the incursion, the Arduino board in turn turns on the buzzer. An effective and secure way to identify intrusions is provided by the system. It is affordable and simple to setup and utilize the system.
