CODE LOCK Presentation Transcript:
1.INTRODUCTION
Digital Code Lock using AT89C2051 is a basic control system with an ability that allows any user having valid user password or Master password to use the system with simple password protection
This code can be changed by the user. This circuit is eminently suitable as a digital lock with security option.
Digital
code lock
is a type
of lock
in which any combination of 5 digits is used to open the lock.
This type of
lock use
numerical code for authentication where the correct code must be entered in order for the lock to deactivate.
The lock can be used with an outdoor gate or a normal door. The functionality of this lock is implemented in software
When the correct code is entered it will open the door. The significant of this project is to eliminate the need for a key.
2.NEED OF CODE LOCK
This kind of lock can avoiding the problems caused by the copying of keys.
On the premise that it’s safety is high, it’s another feature without key is getting more and more favour of people
There are great varieties of digital code locks. Generally speaking, they can be classified into scores of type, such as electronic lock, fingerprint lock, card lock biological lock, etc.
3.OBJECTIVES
To free users from the worry of remembering keys
To design a keyless door entry by using electronic digital lock code
To avoid any crimes especially stealing activities
4.WIRING CIRCUIT
5.ADVANTAGES
WHEN SYSTEM IS BLOCKED AFTER UNSUCCESFUL ATTEMPTS THEN JUST ENTER THE MASTERCODE ,THE SYSTEM WILL BE UNBLOCKED.SO THERE IS NO NEED TO ‘POWER OFF’ THE SYSTEM FOR RESETTING.
THERE IS NO NEED TO ENTER THE SECURITY CODE TO LOCK THE SYSTEM AGAIN, JUST PRESS THE ‘#’ KEY TO LOCK AGAIN.
EVERYTIME THE SECURITY CODE CHANGES IT IS NOT SAME FOR ALL THE CASES , AND THE PERSON WHO KNOW ABOUT THE SYSTEM THOROUGHLY ONLY HE CAN CHANGE THE CODE.SO THIS THING PREVENTS THE SYSTEM FROM HACKING.
6.This digital code lock is therefore particularly useful in applications such as hotel room door locks, residential housing and even office buildings.
We feel that this digital code lock is very marketable because it is easy to use, comparatively inexpensive due to low power consumption and highly reliable
Lock which contained hardware and software development. We also know and understand the microcontroller AT89C2051 and how to implement it on my project
