This project demonstrates how to control a light automatically using a PIR (Passive Infrared) sensor and Arduino UNO. The system is designed to detect motion within the sensor’s range. When motion is detected—such as a person approaching—the light turns on automatically for a few seconds and then turns off if no further motion is detected.

This setup is useful for automatic lighting systems, especially in corridors, bathrooms, stairways, and other areas where manual switching is inconvenient.
