Development of electrical appliance controlling system using bluetooth technology

Abstract

The use of electronic controllers for controlling electrical home appliances can be found widely around the world especially in the developed countries. By time, wireless technology such as infrared light communication. This wireless technology is widely commercialized and can be found almost anywhere. Though appealing, it still has a weakness due to the use of infrared light as data transmission medium. When there are objects blocking the infrared receiver, the process of controlling those electrical appliances becomes difficult due to the point-to-point or line-of-sight communication mode. From this situation, came the idea to create a wireless electronics control system utilizing Bluetooth technology for data transfer and control of electrical appliances. PIC 16F877A microcontroller acts as a “brain” for this system in executing the tasks and operations according to the user’s wish. This system’s Graphical User Interface (GUI) is developed using Microsoft Visual Basic Express to enable the user to control and understand the system in controlling electrical appliances easily.
