Smart Home Automation System

The project is to build a Voice Control Home Automation System Using Arduino and HC-05. This project utilizes a microcontroller and Bluetooth module. A microcontroller is a compact integrated circuit designed to govern a specific operation in an embedded system. So in this system the microcontroller controls the function of the lights. HC-05 module is an easy to use Bluetooth SPP (Serial Port Protocol) module, designed for transparent wireless serial connection setup. This way the lights can be controlled wirelessly with Bluetooth. Here we will control three different home appliances by voice Command. The key components of this project are Arduino, Bluetooth module, Relay module, a smartphone, and Android App. At first, we need to install the app on our smartphone, which is easily available in the play store. This app receives our Voice command and sends it to the Bluetooth module wirelessly. The Arduino decodes this command from the Bluetooth module. Then Arduino sends a command to the Relays to control the home appliances. These four home appliances are switched on/off by eight different voice commands.
