Abstract: This paper presents a comprehensive analysis and implementation of a Home Automation System using relays and microcontrollers. The system allows control of home appliances such as lights, fans, and other electronics via automation protocols controlled by a microcontroller, increasing energy efficiency, safety, and user convenience. The integration of relay modules ensures effective switching capabilities for high-power devices, while microcontrollers act as the central processing unit for communication and decision-making. With the emergence of IoT and smart homes, such systems are becoming integral in modern living environments. The proposed system is economical, easily replicable, and highly scalable for large-scale deployments.
