I, along with my one friend, started this project when I was in my second year and recently started working on microcontrollers, although I preferably worked with AVR atmega series like atmega16, atmega32 and atmega8.So, I wanted to make a project on home automation system to control different household appliances, but there were already some home automation projects based on Arduino and atmega microcontrollers. That’s why I chose this project as something different and more useful and even interesting than other ordinary projects out there.

        I used Bluetooth as communication link between user and appliances because it was universal and easily accessible like we could use our PC and smartphones to interact, which omits additive work for transmitter which is independently done by user’s smartphone. Well, the basic idea behind the project was I chose Google’s voice conversion features which is supported by each device and the string of commands generated by it are transmitted serially to microcontroller, which was in my case was atmega16, with the help of a Bluetooth  module used for receiving from user. Furthermore, we added relays to control appliances and we even added an LCD display to make it look more impressive.
