Fingerprint Door Lock Using Arduino Pdf

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.

Fingerprint door lock using arduino pdf. In this project the arduino uno microcontroller and the. After learning arduino for 2 weeks i decided to diy a fingerprint lock with arduino. 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. Arduino fingerprint door lock with keypad and lcd.

I hope to find a cheap way and do need not change my locks. This project includes a smart and affordable door lock enhanced with a fingerprint interface. But it is not only expensive and it is also very troublesome to install. In the future there could be many more applications like fingerprint based driving licences bank accounts operation and so on.

For implementing this project we will be using the atmel atmega328p a fingerprint sensor gsm module. 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. This system can prove very useful in housing buildings large offices universities and so on.
