The Automatic Light Off System is a smart and energy-efficient system designed to control lights automatically. This project uses an ultrasonic sensor, two Arduino Uno boards, LED lights, a switch, jumper wires, and a 9V battery to operate the system. The ultrasonic sensor detects the presence or movement of a person within a certain distance. When a person is detected, the LED light turns on automatically, and when no presence is detected for a period of time, the light turns off automatically.

The purpose of this project is to reduce electricity wastage and improve energy efficiency by ensuring that lights are only used when needed. The switch allows manual control of the system if necessary. By using automation technology, this system provides convenience, saves energy, and supports smart home applications. This project also helps students understand the practical use of Arduino programming, sensors, and electronic components in developing automated systems.
