Abstract

• In this work, four channels automatic Bluetooth control system is designed and developed. The system consists of the regulated power supply, Bluetooth module, relay drivers and Arduino microcontroller uno board. An Arduino which is an open-source microcontroller board can be controlled or programmed by the computer. The Arduino programming language is used to program Arduino board through serial communication. The firmware program on the Arduino board is controlled by the android application program on the smart phone. Totally, four channels’ appliances are controlled separately from the smart phone.
