Bluetooth Based Smart Home Automation System using Arduino UNO Microcontroller

Abstract

There are different methods in wireless technology such as Bluetooth, WIFI, and GSM. In this paper, new design and different home appliances are presented. Bluetooth Based Home Automation System using Arduino UNO Microcontroller is design and implemented. PWM technique on Arduino is used to control the DC motor speed depending on the width of the Pulses and H-Bridge driver circuit is used to control the direction of the motor. The home automation applications that has presented in this paper is the ability to control the DC motor speed and its direction, bulb, fan and heater using a smart phone application with Bluetooth wireless technology. The relays is used to connect these appliances to the input/ output ports of the board .The design is a low cost, flexible and using a modern technology and devices for this application. Application of wireless Bluetooth connection in control board enables a simplified way to system installation. The system has been built and operated successfully
