This paper presents a practical and efficient method to remotely control a household electrical switchboard using an Arduino Mega microcontroller, a TSOP1738 IR receiver module, an 8-channel relay module, a digital dimmer module, and the IRremote library. The developed system allows users to wirelessly switch household appliances on and off and control the brightness of lights using standard IR remote control devices. By integrating the Arduino Mega and IRremote library, this solution offers ease of implementation, high reliability, and low cost, making it suitable for smart home applications. Experimental results demonstrate effective and accurate remote operations, highlighting the practicality of integrating conventional electrical systems with modern automation technology.
