3. ABSTRACT
• ABSTRACT
• In today’s concurrent world security is the biggest concern.
Therefore to achieve the milestone of safety and security we come up
with the idea to design security systems which can be deployed in
secured zone where only authentic person can get entry. We here have
made use of RFID and Arduino for door lock system. The RFID is the
less expensive and more effective next generation upgrade for door
lock system with the only purpose of safety and security. With the use
of RFID sensor and Arduino we can lock and unlock the door. We
have attached DC servo motor with the door as an additional feature.
This system takes safety to next level.

5. • INTRODUCTION
• This Project provides knowledge on radio frequency identification (RFID)
technology. Initially RFID tags were made to eventually replace barcodes in
different chains. Their advantages are that they can be read wirelessly and with no
line of sight, contain more data than barcodes, and are stronger. As the project
describes the recent technology, include the frequency ranges used and standards
required. With the increase in ubiquity of RFID tags, however, privacy became
unease. The project outlines probable attack that can go against one's privacy and it
also describes contradict measures. The RFID technology did not stop at thing-level
tagging. Since the uses for RFID tags are so extensive, there is a large interest in
lowering the costs for production of RFID tags. It turns out that printing tags may
become a possible alternative to traditional production.

6. • PROPOSED SYSTEM
• Security systems play an important role to prevent unauthorized personnel entry into a secured
environment, which may include physical and intellectual property. Various door locks such as
mechanical locks or electrical locks were designed to attain basic security requirements. Basically,
these locks can be easily hacked by unwanted people thereby allowing unauthorized personnel into
secured premises. speech recognition of the elevator system permits the communication mechanism
between the user and also the Arduino primarily based mechanism. Automatic access control system
has become necessary to overcome the security threats faced by many organizations in Nigeria. By
installing the system at the entrance will only allow the authorized personnel to enter the
organization. The system is not restricted to main entrance installation, but can be installed at various
entrances within the organization to track personnel movement thereby restricting their access to
areas where they are not authorized. There are several automatic access control technologies
including barcode, magnetic stripe and Radio Frequency Identification (RFID) applied in security
system. Radio-Frequency Identification (RFID) is an emerging technology and one of the most
rapidly growing segments of today’s access control. RFID technology, offers superior performance
over other automatic identification systems and is used in many areas such as public transport,
ticketing, animal identification, electronic immobilization, industrial automation, access control,
asset tracking, people tracking, inventory detection and many more

7. • POWER SUPPLY
A power supply is an electronic device that supplies electric energy to an electrical
load. The primary function of a power supply is to convert one form of electrical
energy to another and, as a result, power supplies are sometimes referred to
as electric power converters. Some power supplies are discrete, stand-alone devices,
whereas others are built into larger devices along with their loads. Examples of the
latter include power supplies found in desktop computers and consumer
electronics devices.

8. • TRANSFORMER
A transformer is a static electrical device that transfers electrical energy between two or more circuits. A
varying current in one coil of the transformer produces a varying magnetic flux, which, in turn, induces a
varying electromotive force across a second coil wound around the same core. Electrical energy can be
transferred between the two coils, without a metallic connection between the two circuits. Faraday's law of
induction discovered in 1831 described the induced voltage effect in any coil due to changing magnetic flux
encircled by the coil. Transformers are used for increasing or decreasing the alternating voltages in electric
power applications, and for coupling the stages of signal processing circuits. Since the invention of the first
constant-potential transformer in 1885, transformers have become essential for the transmission,
distribution, and utilization of alternating current electric power. A wide range of transformer designs is
encountered in electronic and electric power applications. Transformers range in size from RF transformers
less than a cubic centimeter in volume, to units weighing hundreds of tons used to interconnect the power
grid.

9. • ARDUINO
• Arduino is an open-source hardware and software company, project and user community that designs
and manufactures single-board microcontrollers and microcontroller kits for building digital devices. Its
products are licensed under the GNU Lesser General Public License (LGPL) or the GNU General Public
License (GPL), permitting the manufacture of Arduino boards and software distribution by anyone. Arduino
boards are available commercially in preassembled form or as do-it-yourself (DIY) kits.
• Arduino board designs use a variety of microprocessors and controllers. The boards are equipped
with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards
('shields') or breadboards and other circuits. The boards feature serial communications interfaces,
including Universal Serial Bus (USB) on some models, which are also used for loading programs from
personal computers. The microcontrollers can be programmed using C and C++ programming languages. In
addition to using traditional compiler toolchains, the Arduino project provides an integrated development
environment (IDE) based on the Processing language project.

10. ARCHITECTURE
• Here Architecture is of Arduino or precisely the IC of Arduino (ATmega328p).
The ATmega328/P is a low-power CMOS 8-bit microcontroller based on
the AVR® enhanced RISC (reduced instruction set computer) architecture. In Order
to maximize performance and parallelism, the AVR uses Harvard architecture –
with separate memories and buses for program and data. Instruction in the program
memory are executed with a single level of pipelining. The clock is controlled by an
external 16MHz Crystal Oscillator.

11. • LCD
A liquid-crystal display (LCD) is a flat panel display, electronic visual display, or
video display that uses the light modulating properties of liquid crystals. Liquid
crystals do not emit light directly.
LCDs are available to display arbitrary images (as in a general-purpose computer
display) or fixed images which can be displayed or hidden, such as preset words,
digits, and 7-segment displays as in a digital clock. They use the same basic
technology, except that arbitrary images are made up of a large number of small
pixels, while other displays have larger elements.

12. • LED
A light-emitting diode (LED) is a two-lead semiconductor light source. It is a pn-
junction diode, which emits light when activated.]When a suitable voltage is
applied to the leads, electrons are able to recombine with electron holes within the
device, releasing energy in the form of photons. This effect is called
electroluminescence, and the color of the light is determined by the energy band
gap of the semiconductor.

13. • DC MOTOR
• A DC motor is any of a class of rotary electrical machines that converts direct
current electrical energy into mechanical energy. The most common types rely on the
forces produced by magnetic fields. Nearly all types of DC motors have some
internal mechanism, either electromechanical or electronic; to periodically change
the direction of current flow in part of the motor.

14. • RADIO-FREQUENCY IDENTIFICATION
• Radio-frequency identification (RFID) uses electromagnetic fields to automatically
identify and track tags attached to objects. The tags contain electronically stored
information. Passive tags collect energy from a nearby RFID reader's
interrogating radio waves. Active tags have a local power source (such as a battery)
and may operate hundreds of meters from the RFID reader. Unlike a barcode, the
tag need not be within the line of sight of the reader, so it may be embedded in the
tracked object. RFID is one method for Automatic Identification and Data
Capture (AIDC). RFID tags are used in many industries, for example, an RFID tag
attached to an automobile during production can be used to track its progress
through the assembly line; RFID-tagged pharmaceuticals can be tracked through
warehouses; and implanting RFID microchips in livestock and pets allows for
positive identification of animals.

15. • CONCLUSION
• RFID based security and access control system is more secure and fast
responded as compared to the other system like biometric. The advantage of the
RFID system is contact-less and works without-line-of-sight. By using arduino it is
easy to access and works very quickly while burning the code it is like plug and
play device. Users can change the function accordingly by using arduino. It is easier
to use and accurate also. Hence this project can be useful for implementation of
access control application for tracking system as well as providing the security
benefits. This project can improve by raising the range of reader in which the tag
read.
