        INTRODUCTION
Our objective is to replace the existing
Mouse based technology with a simple TV
Remote

It’s a sort of blend between two giants of
Engineering viz ELECTRONICS &
SOFTWARE Engineering


              http://www.final-yearprojects.co.cc/
               http://troubleshoot4free.com/fyp/
Provision of GUI using a TV Remote
The whole set-up being completely handy
and workable
Easily interfaced with any computer
system
Brainchild of all the group members



             http://www.final-yearprojects.co.cc/
              http://troubleshoot4free.com/fyp/
Highly portable hardware employed
Software based on Visual Basic
Programming Language
Movements of the ‘cursor’ controlled by
the remote

RS-232 CONNECTOR
SIMPLE TV REMOTE




         http://www.final-yearprojects.co.cc/
          http://troubleshoot4free.com/fyp/
              TSOP IC
-Thin Small Outline Package
Consists of a PIN Diode & Pre-amplifier
Center frequency of 38 kHz
Working similar to a Band Pass Filter




             http://www.final-yearprojects.co.cc/
              http://troubleshoot4free.com/fyp/
    BYPASS CAPACITOR
Used for the smoothening of Power
Supply
Even small fluctuations unwanted for a
digital circuitry
Capacitors used-Electrolytic (for small
energy & high capacitance) and Ceramic
(high frequency operation)


             http://www.final-yearprojects.co.cc/
              http://troubleshoot4free.com/fyp/
            MAX-232 IC
Used as a Voltage Controller IC
Conversion of Source code i.e Remote
control signal to it’s equivalent ASCII Code
It’s a dual driver/receiver




              http://www.final-yearprojects.co.cc/
               http://troubleshoot4free.com/fyp/
MICROCONTROLLER ASSEMBLY
 Microcontroller being AT 89c2051
 Part of Atmel 89c family
 2.7 to 6V operating range
 2kB of PEROM
 128*8 bit Internal RAM




              http://www.final-yearprojects.co.cc/
               http://troubleshoot4free.com/fyp/
15 Programmable I/O Lines
Two 16 bit Timer/Counter
20 Pin DIP (Dual Inline Package)
CMOS 8 bit Microcontroller




             http://www.final-yearprojects.co.cc/
              http://troubleshoot4free.com/fyp/
How to burn a Microcontroller
Need a Programmer Board
An Application Software
Feed that Software on the internal memory
of the microcontroller and that’s it..




             http://www.final-yearprojects.co.cc/
              http://troubleshoot4free.com/fyp/
    RS-232 CONNECTOR
-Recommended Standard 232
Used as a Serial Interface
Connects a DTE (Data Terminal
Equipment) to a DCE (Data
Communication Equipment)




            http://www.final-yearprojects.co.cc/
             http://troubleshoot4free.com/fyp/
Four Control Lines: RTS,CTS,DTR,DSR
Demerits: Observed Large Voltage Swings
Requires +ve and –ve voltage levels
Converts +10 & -10V levels to +5 & -5V
