Bluetooth-Based Home Automation System Using an Android Phone

Implementation of home automation using the latest technology gives us more convenience, security and safety. smartphone affordability increases every year and smartphones have begun to play important roles in our daily lives due to their size and portability. google’s android operating system (os) is one of the leading and most preferred smartphones. controlling home appliances by using an android phone gives users the ability to control their home appliances anywhere and at any time while at home and saves time spent in searching for the remote control unit of home automation systems since the user’s phone is usually kept close at hand. this project presents the design and implementation of a low cost prototype of a bluetooth-based home automation system using an android phone. the design uses an arduino mega 2560-r3 board and the home appliances are physically connected to input/output ports of this board via relays. cytron bluebee is used to establish wireless communication between them. bluetoothhome, an android application, is developed to provide a user friendly graphical user interface (gui) for the remote control of home appliances.
