INTRODUCTION

Conventionally,we can secure our home. This project will work as a gate keaper

This system is operate when we enter the right code.

If we enter the wrong code more than 3 times gate will never open.Only right code is granted.

PROJECT OVERVIEW

SCHEMATIC OF HOME SECURITY SYSTEM

CIRCUIT DESCRIPTION In this project,LED is used in place of Gate.Keypad is used to enter the numeric code ie keypad is used as an input device .16X2 LCD is used as an output.We can see entered code in this LCD.AT89C52 Microcontroller is used here to get input & display the output on LCD.Crystel 11.0592 MHz is used to provide the clock pulse

SOFTWARE USED KIEL-3:This is Microcontroller code compiler.

PROTEL-99SE: This is PCB design Tool.

SOFTWARE DESCRIPTION We can also write software in ‘C’ language

and compiled using KIEL-3 compiler . The source program is converted into hex code by the compiler. Burn this hex code into AT89S52.The source program is well commented and easy to understand. Set port A as the input and port D as the output. The program will run forever by using ‘while’ loop. Under ‘while’ loop, read port A and test the received input using ‘switch’ statement. The corresponding data will output at port D after testing of the received data.
