The mobile application offers a tool that helps facilitate the user in everyday life, such as finding out the purchase - sale transactions, finance, marketing, as well as command and control applications. Which is often a problem in several ways, be it. The equipment used in the connection. Limited in time and distance, or crash the user's own Broad (PCB: Printed Circuit Board), and also facilitates the users as well.
From the above reasons, the research is the development of mobile application control electrical devices to home via Bluetooth Signal. A device called a PCB board is set to receive a microcontroller-signaling and control on–off. The device is installed through the channels assigned to them in the PCB board, and also facilitates the users as well.
