ELECTRONIC CODE LOCK
The aim of this project is to interface 4x16 LCD, 4x4 Matrix Keypad, Motor and Power Supply with 8051 Microcontroller and provide a simple low-cost electronically operationlised door.
A keyless electronic combination lock is adaptable for placement on a door, and operates independently of any other locks and without a central control system. The lock has an 8051 Microcontroller, 4x4 matrix keypad for entering combinations, motor to move the door, 4x16 LCD to display the process of Electronic Code Lock...............etc

TITLE : DIGITAL CODE LOCK
INTRODUCTION
Here is a project called ˜Digital Code Lock using AT89C2051'. LCD is used for display and a keyboard is used to input the keys. This project source code is written in C.This a simple project with efficient hacking prevention from Brute Force etc. The basic user lock is of 5 Digits and Master Lock is of 10 digits so its not easy for an intruder to break the lock unless you keep the code simple.The input is taken from a 4×3 Keypad (please see the sc..............etc

Microcontroller Based Digital Code Lock
ABSTRACT
Security is a prime concern in our day-today life. Everyone wants to be as much secure as possible. An access control for doors forms a vital page link in a security chain. The microcontroller based Door locker is an access control system that allows only authorized persons to access a restricted area. The system is fully controlled by the 8 bit microcontroller AT89C2051 which has a 2Kbytes of ROM for the program memory. The password is stored in the EPROM ..............etc

A Brief Description:
This project is written in C language. Its a simple project with efficient hacking prevention from Brute Force etc. The basic user lock is of 5 Digits and Master Lock is of 10 digits so its not easy for an intruder to break the lock unless you keep the code simple.The input is taken from a 4x3 Keypad (please see the schematic for more information) and Display the user input on a 2x16 LCD. A pin is assigned as output for activating and deactivating the lock. For demonstration i have connected an LED to that pin.
