This project combines ambient light sensing with automated actuation to open or close a window based on real-time light intensity. Using an LDR (Light Dependent Resistor) sensor and a servo motor connected to a Raspberry Pi 5, learners will build a responsive system that supports energy efficiency. When light is present, the servo opens the window, promoting ventilation and natural lighting. When light is absent, the window closes, helping conserve heat or reduce cold airflow. This activity blends sustainability goals with foundational IoT principles.
