ABSTRACT
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 8 bit Microcontroller AT89C2051 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.
The Following functions can be done with PC Remote control.
* All Numerical Keys (0 - 9)
* Arithmetic Keys (+, -, /, *)
* Enter, Escape, Help, Refresh, Caps lock, Tab, Back space, delete, Left, Right, Up, down arrows, Page up, Page down, Window keys.
* Calculator, Notepad
* CD drive Open/Close
* Control panel
* Computer log off, reboot or shutdown
* Volume Up, down, Mute
* 5 User defined Programs
INTRODUCTION
The project aims to development of a PC remote control. This device helps to have better control of computer without mouse and keyboard. As a result they can be avoided and their 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 AT89C51 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.
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. Such devices can be easily attached to computers. PC remote control has become an indispensible component of modern desktops and laptops.
The Following functions can be done with PC Remote control.
* All Numerical Keys (0 - 9)
* Arithmetic Keys (+, -, /, *)
* Enter, Escape, Help, Refresh, Caps lock, Tab, Back space, delete, Left, Right, Up, down arrows, Page up, Page down, Window keys.
* Calculator, Notepad
* CD drive Open/Close
* Control panel
* Computer log off, reboot or shutdown
* Volume Up, down, Mute
* 5 User defined Programs
PROJECT DESCRIPTION
The Main Part of the system is designed by using the Microcontroller AT89c2051. The infrared receiver have three pins in which two pins are for +5v supply and ground while the third pin is for data output. The Infrared Receiver is designed for demodulating the frequency of 30khz to 40khz, for example, TSOP1838 is designed for demodulating frequency of 38khz which is used in our project.
The IR receiver module receives the data sent by remote handset, amplifies, demodulates and converts it to MCU compatible voltage format and outputs it on its data output pin. The microcontroller decodes the infrared signal data and the microcontroller will sent the infrared Key code to the PC through the Serial port.
We use Microsoft Visual Basic 6.0 to receive the Key code through the Component called MSCOMM which is an component for the Com port control. Through this component we get the key code and do the appropriate functions.
After getting this key code of the Remote control the program compare the keycode with the code present in the program and if they are equal then the corresponding function was done.
