Arduino Fingerprint Door Lock Project Pdf

For this project we will use the softwareserial library in the code.

Arduino fingerprint door lock project 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. I hope to find a cheap way and do need not change my locks. For making fingerprint door lock you need arduino uno adafru. After learning arduino for 2 weeks i decided to diy a fingerprint lock with arduino.

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. But it is not only expensive and it is also very troublesome to install. 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.

Here all the process is commanded by arduino like taking an image of finger print convert it into templates and storing location etc. Having them run off battery enables the system to keep running even during a black out. From outside the door a person is greeted with a fingerprint sensor and a display saying if the door is locked or unlocked. Here we are using 4 push buttons to enroll back delete ok up and down.

The whole system is run with dual arduino unos and powered by portable battery packs.
