This document describes a home automation system that allows control of home appliances via voice commands or a mobile app using an Arduino, Bluetooth module, and relay board. The system aims to provide a low-cost, user-friendly way to automate a home. The system uses an Arduino Nano microcontroller connected to a Bluetooth module for wireless communication with a mobile app. A relay board acts as an electrically operated switch to control appliances. The mobile app and voice commands send signals to the Arduino via Bluetooth which processes the commands and controls the relay board to operate appliances. The system was tested and found to efficiently and accurately control appliances with a simple interface.
