ABSTRACT
This paper represents how your PC and Laptop can be controlled from with your T.V remote with the help of Frontend Application. It means the conventional PC mouse operations controlled by using T.V Remote. It turns your Remote into a wireless mouse and don’t need any surface. It requires Forntend application on your computer. This is an implementation of RC5-remote reception on an 8051 micro controller. The received code is decoded and sent to the PC IR remote software written in Visual Basic. The cursor position is moved according to the keys pressed. There are two modes of operation one is as mouse control and second is Windows media player control without monitor running. The convenience of selecting TV channels using your remote and then pointing the same remote to your Computer so that you can control the whole system using the single remote control. The 8051 microcontroller is used to control all the system. An integrated Infrared Receiver is used to receive the infrared signal from the remote control handset. The received infrared signal was decoded by using the program, which was written on the ROM of the Microcontroller. The programs are flashed on the ROM area of the Microcontroller. The Flash memory is a type of EEPROM. The Details of the switch pressed was sent to the PC through its serial port. In the PC, Visual Basic was used to control the PC through the API functions.

1. INTRODUCTION
Consumer electronics devices and personal computers have become inevitable part of our life. Similarly, mobile devices and computers like CELL PHONEs and Tablets are becoming more and more commonly used in our daily life. Controlling consumer electronics devices and computers remotely is an important aspect of the technology. Today, we have remote control devices to control
consumer electronic devices such as DTMF sets. Similarly, it is desirable to remotely control stationary desktop/laptop PCs and their applications. Which offers a wireless means of communication between the computer and the user and also helps to overcome the disadvantages of wired and wireless mouse. For ex- ample, an instructor in class-room may want to control a PowerPoint presentation running on his laptop computer and projected on the screen using a TV Remote (i.e. wireless mouse). Our application will be primarily based on .Net Technology [4]. The one side of the system runs on top of the Windows operating system [1] and the other side is a .Net based application built in IR technology.
Controlling of electrical appliances through IR remote is interesting and very useful application. This system is widely useful to industries, offices, Banks, hotels, hospitals, and display boards. In this, IR remote is used for controlling PC\Laptop in your room. We identified the following as the requirements of a system that enables a TV Remote to be used as a remote control device for desktop PC while he is moving around in the class-room freely. In this way, he does not have to go to the laptop each time when he wants to use the Power Point screen. Its architecture is based on IR Transmitting - Receiving paradigm. It consists of two parts: a transmitter part and a recevier part. The transmitter part is known as TV Remote. The recevier part consists of microcontroller, TSOP Receiver, serial communication and PC. This side of the system is capable of listening incoming connections, sending and receiving data, processing control, commands taking screenshots, modify applications [5].
This device helps to have better control of computer without mouse. As a result mouse can be avoided and mouse functions are incorporated in the PC remote control. The commands made by the user through the PC remote control is read and interpreted by the 8051 microcontroller. The button pressed in PC remote control by the user will be detected by microcontroller based circuit and these details are sent to PC via RS232.It can be also used for windows media player functioning. PC remote control is basically an alternative for a mouse. PC remote control offers a wireless means of communication between the computer and the user. PC remote control helps to overcome the disadvantages of wired and wireless mouse [1]. Such devices can be easily attached to computers. PC remote control has become an indispensable component of modern desktops and laptops.
2. OBJECTIVE
1. It operates PC\Laptop from our living room using with key pad inputs of TV Remote.
2. It allows a power button, as well as a switch or series of buttons to select which device the remote is controlling at the moment.
3. It allows a numeric keypad for moving the mouse cursor.
4. It allows Arithmetic Keys for controlling media player and slider also.
5. It allowing the user to program command sequences to 5 User defined Programs.
6. It allowing the remote to be programmed to control new devices not already in its code list by IR coding
7. Accept infrared signals from any remote and transmit them to the device being controlled using repeater.
3. DEVELOPMENT PROCESS
This paper is about how to control PC applications remotely inside a house, an office, or a conference room. As the remote control device, we consider using a TV Remote with Visual Basic capability. For this purpose, we have designed and implemented a frontend application, called Remote Control that enables a Remote to act as a remote controller device for desktop PCs and their applications. In this paper, we introduce of, its architecture, and how we have realized it.
