ACKNOWLEDGEMENT

This project is dedicated to our Parents who have never failed to give us financial and moral support, for giving all our need during the time we developed our system and for teaching us that even the largest task can be accomplished if it is done one step at a time.

I dedicate this dissertation to my family, especially…
To our Mother and Father for opening my eyes to the world;
To our professors for their patience and understanding;
To our friends for instilling the importance of hard work
and higher education;
To all the people who helps us accomplish this work
We all thank you.

SUMMARY

This device is a computer based as an access control. You can use the device by automatically locking or opening each door on a certain place using a computer. You can control the door if you want to lock it or open it. This device can also use scheduling for a simple and better performance. It can also be access using biometrics on a register fingerprint.

An automatic door operating system includes a computer connected to operate a door by means of a unidirectional linkage system including the microprocessor and actuator for unidirectional engagement of the door and a control system for selectively opening the door and for controlling the duration of the door open position. The control system includes a variable timing release for variable timing of the duration of the valve opening. The actuator for the system can be remotely positioned for maintaining the door in open position for sufficient duration to permit passing. The linkage system permits the door to be manually operated totally independent of the operating system or using biometrics. It can be also automatically operated by using a program and scheduling it for some purposes.

INTRODUCTION
An electronic lock is a locking device which operates by means of electric current. Electric locks are sometimes stand-alone with an electronic control assembly mounted directly to the lock. More often electric locks are connected to an access control system. The advantages of an electric lock connected to an access control system include: key control, where keys can be added and removed without re-keying the lock cylinder; fine access control, where time and place are factors; and transaction logging, where activity is recorded. Electric locks use magnets, solenoids, or motors to actuate the lock by either supplying or removing power. Operating the lock can be as simple as using a switch, for example an apartment intercom door release, or as complex as a biometric based access control system. The most basic type of electronic lock is a magnetic lock (commonly called a mag lock). A large electro-magnet is mounted on the door frame and a corresponding armature is mounted on the door. When the magnet is powered and the door is closed, the armature is held fast...
