This document describes a wireless home automation system using an Arduino, Bluetooth module, and relay board. A group of students built a system to control appliances remotely using a smartphone app. The system allows controlling devices from a distance wirelessly and provides a low-cost way to create a smart home network where appliances can communicate with each other. It connects an Arduino board with a Bluetooth module to a relay board to control AC loads like lights, fans and switches remotely through an Android app.
