Abstract:
This project presents a Bluetooth-based wireless control system using a Raspberry Pi and relay module. The system allows for the remote operation of four electrical devices via simple command signals sent from a Bluetooth-enabled device (e.g., smartphone or laptop). Commands received over an RFCOMM Bluetooth connection are interpreted by the Raspberry Pi to control the GPIO pins, which in turn activate or deactivate relays. The project demonstrates an efficient and cost-effective approach to building a home automation or industrial control system, emphasizing simplicity, real-time control, and scalability. Applications can include smart lighting, appliance management, and remote switching systems.
