Abstract
This study presents the design and implementation of a cost-effective smart home automation system based on Arduino Nano and Bluetooth technology. The system integrates multiple household appliances into a unified control platform accessible via smartphone. The hardware configuration includes an Arduino Nano microcontroller, HC-05 Bluetooth module, relay modules, and a regulated power supply, while the software framework was developed using the Arduino IDE. Both simulation and practical implementation demonstrated reliable appliance switching—such as light bulbs and fans—within the effective Bluetooth range, with stable voltage regulation and real-time responsiveness. The proposed system enhances convenience, safety, and energy efficiency, offering benefits for the elderly and physically challenged. However, limitations were observed, including the restricted communication range of Bluetooth and the absence of cloud connectivity for remote access. Future work will address these challenges by incorporating multi-protocol interoperability, cloud integration, and advanced security features, thereby expanding the system’s scalability and reliability for broader smart home applications.
