ABSTRACT
Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system. These techniques are an integration of mechanical and electronic devices and highly intelligent. One of the prominent features of these innovative lock systems is their simplicity and high efficiency.
Such an automatic lock system consists of electronic control assembly which controls the output load through a password. This output load can be a motor or a lamp or any other mechanical/electrical load.
Here we develop an electronic code lock system using arduino, which provides control to the actuating the load. It is a simple embedded system with input from the keyboard and the output being actuated accordingly.
This system demonstrates an RFID and bio metric based door lock system wherein once the correct RFID card and finger print is entered, the door is opened and the concerned person is allowed access to the secured area. Again if another person arrives it will ask to enter RFID card or finger print. If the RFID card or finger print is wrong then door would remain closed, denying the access to the person.

CHAPTER ONE
1.1 INTRODUCTION
The security situation in many parts of the world today leaves much to be desired. In Nigeria particularly, the prevalence of armed robbers and other groups that constitute nuisance to the society has led to the loss of lives and properties worth millions of dollars. Many of the attacks that led to the loss have occurred in the homes or in guarded compounds and the attacks took place in spite of the existence of seemingly impregnable security gates that were designed to ward off intruders. The needs for electronically controlled gates that have superior security features to those operated manually thus exist and have been on the increase in recent times.
This device consist of a card reader, Electromagnetic lock or door strike. Power supply system and a push button. To use this system, the authorized card user when approach the reader will just have to use the card key or pin number. Once the correct data is present to the reader system, through an interface the locking / door holding devices will be de-energized and the door can be push open. From inside of building to exit the building the person will just have to press a door lock release switch and the system will release the lock. A power back-up unit will be incorporated into most access control system, this will act as standby power in the event there is a power outage. For certain safety requirement a break glass is incorporated into the system for emergency release of the door.
This device is better than the password based access controlled in the sense that passwords belonging to one individual can be learned by another without the owner’s permission. This device uses Radio frequency identification and finger print. Radio frequency identification (RFID) has been used in conjunction with microcontrollers to control gates. This system is only required to close and open gates and has a very limited security feature. In the work done by Adewuyi et al. [11, 12] surveillance cameras are used to capture and recapture the face of the driver as well as vehicle plate numbers. These data are stored in a databank for future comparison with visitors who will only be able to gain entry into a compound through gates if the data match. The system has the disadvantage that users must have been properly documented to enable them pass through the gate.
The system that has been designed in this work uses arduino, radio-frequency transmitter/receiver pair as major components, and a rfid reader. Some advantages of the system include:
(i) It does not need close contact to control the gate; the control can be done from inside the car at a distance.
(ii) It operates as a stand-alone system and does not require a network provider for reception of signals.
(iii) The use of an rfid card to generate the code necessary for the opening and closing of the gate enhances the security of the system since it requires very many trials by an intruder to succeed in breaking into the system.
(iv)The features of the system that are controlled by the firmware resident in the memory of the arduino can be easily improved for future upgrade.
(v) it has only one access controlled unit, that is, using RFID card
1.2 OBJECTIVE OF THE PROJECT
The main objective of this project is to develop an embedded system, which is used to verify and authenticate the authorized person entering a restricted room or area. This verification is done via RFID card.
1.3 PURPOSE OF THE PROJECT
Main purpose of the Access Control is to begin with – protect physical, IP and human assets. This requires restricting unauthorized people from reaching pre-defined areas. This security can be achieved by using RFID card when the user approaches the entrance door where the access controlled door is been used.
1.4 BENEFITS OF THE PROJECT
- Control Access based on User, Zone and Time
- Secure Sensitive Areas with Advanced Access Control Features
- IP based Architecture to Enhance Reliability and Scalability
- Centralized Monitoring and Control of Multiple Devices and Locations
- Get Real-time Notification on Exceptions
1.5 SIGNIFICANCE OF THE PROJECT
- This project provides security
- Power consumption is less
- Used commonly available components
- Project is simple and easy
- This device makes provision for alternative access for the user. For example if the user forgets the RFID card, then the finger print can be used to have access to the place he wants to enter.
1.6 APPLICATIONS OF THE PROJECT
· This simple circuit can be used at residential places to ensure better safety.
- It can be used at organizations to ensure authorized access to highly secured places.
- With a slight modification this Project can be used to control the switching of loads through RFID card.
1.7 SCOPE OF THE PROJECT
The main component in the circuit is the controller, RFID transmitter/receiver, and rfid reader.
RFID based security system using Arduino project has a RFID reader attached to it. RFID reader reads the unique alphanumeric code of RFID tags and sends it to Arduino. Then Arduino detects whether RFID card is valid or invalid. If the card is invalid then system turns on the buzzer. However, if the RFID card shown by the user is valid then the DC motor is turned on and at the same time Relay is turned on. DC Motor is shown as a demo of door lock (latch) opening. Also, Relay is provided as an additional feature so that user can connect any electromagnetic security lock to the system if required.
1.8 LIMITATIONS OF THE PROJECT
· It is a low range circuit, i.e. it is not possible to operate the circuit remotely.
- If there is no power supply and the battery is not charged, it is not possible to open the door.
