Abstract
The increasing demand for energy-efficient and intelligent home automation systems has led to significant advancements in smart electrical control solutions. This paper presents a comprehensive design and implementation of a Smart Electrical Switchboard utilizing an Arduino Mega microcontroller, a 4x4 keypad, an array of 8 relays, and a digital dimmer module. The proposed system aims to enhance user convenience, reduce power consumption, and enable precise control over various household electrical appliances. Users can conveniently operate appliances via the keypad, enabling manual input for turning devices on/off and adjusting the brightness levels of dimmable lighting systems. The relay modules provide effective on/off switching capability, while the digital dimmer module facilitates smooth intensity control of connected devices, particularly lighting. The Arduino Mega coordinates these components, integrating user input and providing robust, reliable operation. Experimental results demonstrate the system's efficiency, ease of use, and practicality in real-world residential scenarios, highlighting its potential for widespread adoption in modern smart homes.
