Fingerprint Door Lock Using Arduino

Not only to ensure door security this project also make certain to assist in fields like forensics crime investigation personal identification attendance system and there is a lot more.

Fingerprint door lock using arduino.

I am using fingerprint module r307 and lcd together. It uses a keypad and fingerprint scanner to grant a user access by controlling an electric door s. In this project we will learn how to make password based door lock security system using arduino keypad as thefts are increasing day by day security is becoming a major concern nowadays. Using pwm the master can send different voltages to the slave.

How to make fingerprint door lock at home from this tutorial you can make awesome fingerprint sensored locking system for your door. So a digital code lock can secure your home or locker easily. But it is not only expensive and it is also very troublesome to install. The project arduino fingerprint sensor lock is simply fabricated around arduino board.

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. Arduino fingerprint door lock with keypad and lcd. Therefore there is one master arduino which controls the servo oled and fingerprint sensor while a slave arduino controls the leds. Hello and welcome to this project actually it includes two projects but they re pretty much the same it s a door lock system based on an arduino uno board fpm10a optical fingerprint sensor and a lcd i c screen but for the other version we inclu.

You need adafruit finge. After learning arduino for 2 weeks i decided to diy a fingerprint lock with arduino. 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. 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.

First of all connect the fingerprint sensor to the arduino uno. I hope to find a cheap way and do need not change my locks. Make sure you get a fingerprint sensor that works with the arduino through the serial communication.
