INTRODUCTION : �
* In this project we are going to build a fingerprint door lock system using Bluetooth module and In this project we need Arduino nano , solenoid lock and android Smartphone.
* An android application is designed which scans and varying the fingerprint and sends conformation data to Arduino through Bluetooth serial communication . This system uses smartphone fingerprint sensor is to lock and unlock the door
* The project is made using Arduino Nano Programmer.
* Programming is done using Arduino Software in modified embedded C language.
TECHNOLOGY USED :
In this project we have used an Arduino nano base around the microcontroller . Along with it we will using Hc-05 for Bluetooth communication with the controller app also we are using solenoid lock
COMPONENT LIST :
1 Arduino nano 5 Relay module
2 Hc-05 Bluetooth module 6 Buzzer
3 Solenoid lock 7 Jumper wires
4 9,12v battery 8 Breadboard
ARDUINO NANO : �� �* The Arduino nano is a small , complete � and breadboard –friendly board based on� the AT mega 328 It has more or less �same functionality of the Arduino .��� * It has only dc power jack and work with� mini- B USB cable instead of a standard one .�� �* Features : � It has 22 input and output pins in total � 14 of those pins are digital pins � 8 of the analogue pins � input voltage is 7 to 12 v�
HC-05 BLUETOOTH MODULE :� � * It is used for wireless headset , game controller ,� wireless mouse , wireless keyboard, and� many more consumer application .�� * It has range up to <100 m witch depends upon� transmitter or receiver it is IEEE 802.15.1� standardized protocol �� * It uses serial communication to � communicate with device . �� * Power supply: +3.3VDC 50mA�
SOLENOID LOCK :��* The solenoid lock denotes a latch for� electrical locking and unlocking . �� * You can interface this electromagnetic� lock to any micro-controller or Arduino� using a simple relay, If you want you can� directly use a one channel relay driver module.��* Solenoids are basically electromagnets��* They are made of a big coil of copper �wire with an armature in the middle��features:- 1 iron body material� 2 high quality ultra-compact electric lock.

CIRCUIT DIAGRAM :
:-
Circuit assembly for this project is very simple. Here we are only connecting a Bluetooth Module, a relay module, and a buzzer with Arduino Nano. The VCC and GND pins of the Bluetooth module are connected to 5V and GND of Nano while Tx and Rx pins are connected to Rx and Tx of Arduino Nano respectively. Similarly, the input pin of the relay is connected to the Digital pin 9 of Arduino Nano while VCC and Ground pins are connected to the 5V and GND pin of Arduino Nano. The positive pin of the buzzer is connected to Digital pin 7 of Arduino and the negative pin is connected to the GND of Arduino Nano.
SOFTWARE REQUIRED :
ARDUINO IDE :
* The Arduino integrated development environment is a cross platform application that is written in functions from C and C++
* it is used to write and upload program to Arduino compatible boards but also with the 3rd party cores other vendor development boards.
* Arduino IDE is require to write compile and uploaded the code of the project.
ADVANTAGES �����������
* Cheap, compact and feasible.
* Easy to programme and use with a single board.
* Easy mountable on small area and can be operated by small voltage.(5v -9v).
* Low power consumption.
* Simple circuitry.
DISADDVANTAGES
* Performance drops with long term usage.
* Moisture and heat can affect the performance of the circuit and functionality of the system
The security lock can be designed in following manners��*password protected security lock.�*RFID recognition.�*WIFI connection with server.�*Ethernet connection to the LAN.�*The most secure way-biometric (fingerprint) scanning.��������
FUTURE EXTENSIONS
� CONCLUSION � � we have tried to solve the security matter in door by bringing the concept of biometrics along with the door lock. So, for that purpose we are using finger prints as unique key to implement a device so as to lock or unlock a door. We have discussed about the different components using Arduino we would require to implement our project i.e we have given the hardware and software requirements in the project. We have gone through different research papers and then given a brief about the papers and after studying the papers we have come with an algorithm as to how our system will work. We have also given a project description diagram and also a cost structure so as to get to a price if it is sold as a product. We have shown a block diagram and a �probable connected diagram of the components and also given the future possibilities in our project�
