Abstract
A remote control is a component of an electronics device, most commonly a television set, DVD player and home theater systems originally used for operating the television device wirelessly from a short line-of-sight distance. But sometimes it will be more comfortable if a person using PC/laptop gets the power of controlling devices in his room, office or anywhere without using remote just by a mouse click in software. We have designed and implemented a prototype system for on/off switching of electrical appliances through an AT89s51 Microcontroller. Hardware includes microcontroller (8051), relays & USB com port for serial communication. We have designed code in visual basic for turning on/off the appliances connected to microcontroller. Operation of the application is very simple. When we press ON switch in software, which is created in Visual Basic, it sends a command to AT89s51. Now controller will turn ON the device based on logic developed & programmed in microcontroller. Thus we can turn ON & OFF various devices just by a simple mouse click in software. We have used a serial virtual USB com port to interface microcontroller with PC/laptop.
