After learning arduino for 2 weeks i decided to diy a fingerprint lock with arduino.
Fingerprint door lock using arduino pdf.
Open your door with a special knock using arduino android phone and 1sheeld.
But it is not only expensive and it is also very troublesome to install.
Fingerprint based door lock our proposed fingerprint based lock system is a reliable and very secure lock that will not only ensure safer environment but also ease lifestyle.
Introductionthe fingerprint door lock as the name suggests is an electronic door lock that can be installed on almost any access point in your house.
This system can prove very useful in housing buildings large offices universities and so on.
This project includes a smart and affordable door lock enhanced with a fingerprint interface.
For implementing this project we will be using the atmel atmega328p a fingerprint sensor gsm module.
A fingerprint lock would be help for me and there are plenty of these kinds of locks on the market as the picture above.
Make sure you get a fingerprint sensor that works with the arduino through the serial communication.
The project arduino fingerprint sensor lock is simply fabricated around arduino board.
Because it offers the flexibility to add more features to the system.
I hope to find a cheap way and do need not change my locks.
No one can able to see where the lock from outside the door.
Project tutorial by.
First of all connect the fingerprint sensor to the arduino uno.
It uses a keypad and fingerprint scanner to grant a user access by controlling an electric door s.
This smart lock allows create rules and scheduled actions with your voice using alexa and a new unlock feature using smartphone fingerprint.
This simple fingerprint door unlock project using arduino can be very useful for door security forensics crime investigation personal identification attendance system and much more.
The default pins for serial communication on the arduino uno are pin 0 rxd and pin 1 txd of the board but we are going to use other pins for serial communication.
I am using fingerprint module r307 and lcd together.
In that i am using 2 3 digital pins of arduino for data transfer to the fingerprint i tried other pin configurations for this but it didn t work but as i am connecting lcd it also requires same 2 3 digital pins of arduino and it is not possible for me to use 2 and 3 pins of arduino for both lcd and fingerprint sensor for data transfer.
Open the arduino ide open the file sketchbook enroll you will see the enroll code that function as a fingerprint registration.
After downloading the sketch enrollto crowduino open the serial monitor and set the baud rate to 38400 you will see the outputs from the serial monitor to.
