Fingerprint door lock using arduino pdf.
First of all connect the fingerprint sensor to the arduino uno.
From the code to the various hardware parts of the digital door lock.
Adafruit fingerprint finger adafruit fingerprint myserial.
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.
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.
Arduino fingerprint door lock with keypad and lcd.
A fingerprint lock would be help for me and there are plenty of these kinds of locks on the market as the picture above.
In this project the arduino uno microcontroller and the.
For implementing this project we will be using the atmel atmega328p a fingerprint sensor gsm module.
It uses a keypad and fingerprint scanner to grant a user access by controlling an electric door s.
Because it offers the flexibility to add more features to the system.
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.
This project includes a smart and affordable door lock enhanced with a fingerprint interface.
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.
In the future there could be many more applications like fingerprint based driving licences bank accounts operation and so on.
