Fingerprint Door Unlock System Using Arduino

In this video i show you how to use the fingerprint scanner for a door lock using arduino uno.

Fingerprint door unlock system using arduino.

To make this circuit more reliable and convenient the design of pcb has been done as an arduino shield. 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 the future there could be many more applications like fingerprint based driving licences bank accounts operation and so on. 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.

Fingerprint recognition is one of the most secure systems because a fingerprint of one person never matches with the others. 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. Therefore unauthorized access can be restricted by designing a lock that stores the fingerprints of one or more authorized users and unlock the system when a match is found.

Open the arduino ide open the file sketchbook enroll you will see the enroll code that function as a fingerprint registration. In this post we will interface a fingerprint sensor module with arduino and will build a fingerprint based biometric security system with door locking. To enhance the system i ve also installed a small oled display on the outside of the door to show the system s status i e. After learning arduino for 2 weeks i decided to diy a fingerprint lock with arduino.

It uses a keypad and fingerprint scanner to grant a user access by controlling an electric door s. Finger print is considered one of the safest key to lock or unlock any system as it can recognize any person uniquely and can t be copied easily. Arduino fingerprint door lock with keypad and lcd. 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. Therefore i installed an optical fingerprint sensor on the outside of the door that can also toggle the locked versus unlocked position of the servo. For making fingerprint door lock you need arduino uno adafru. Construction and testing of arduino fingerprint sensor lock the figure 3 and figure 4 reflect the actual size of single side pcb layout for the fingerprint door unlock system and its component layout respectively.

First of all connect the fingerprint sensor to the arduino uno. Bio metrics authorization proves to be one of. Now i need to store my fingerprint to crowduino to let it open the door as i press the fingerprint.
