This document discusses a smart home project using an Android app. The project uses an Arduino Mega, servo motor, Bluetooth module, relay module, and other components to control home appliances like lights and door locks from a mobile phone. It works by connecting the Android phone to the Bluetooth module, which receives and transmits data to the Arduino. The Arduino then uses relays to control 220V appliances with 5V signals based on instructions from the app. A light dependent resistor is also used for intelligent light switching. The document outlines the components, hardware and software used, working mechanism, block diagram, and lessons learned from building the project.
