Home automation using Android offers a smart, user-friendly solution for controlling household appliances via mobile devices. This project integrates an Android app with an Arduino microcontroller and HC-05 Bluetooth module to enable wireless control of lights, fans, sockets, and door locks. Users can access the system through a password-protected interface and receive real-time status updates. The Arduino communicates with the app using serial data through Tx/Rx pins. A DC motor driver (L298N) powers a fan, while LEDs represent lighting and socket control. Each device responds to button presses in the app, visually confirming successful operations. A servo motor handles door locking, rotating between 0° and 180° to open or close. The system demonstrates efficient use of embedded hardware and mobile software for secure, automated living. Overall, it showcases the versatility of Arduino in real-world IoT applications.
