Fingerprint Door Lock Using Arduino

I hope to find a cheap way and do need not change my locks.

Fingerprint door lock using arduino.

Arduino fingerprint door lock with keypad and lcd. After learning arduino for 2 weeks i decided to diy a fingerprint lock with arduino. First of all connect the fingerprint sensor to the arduino uno. You need adafruit finge.

A fingerprint lock would be help for me and there are plenty of these kinds of locks on the market as the picture above. Testing the fingerprint door lock using arduino project. Make sure you get a fingerprint sensor that works with the arduino through the serial communication. Conclusion in this tutorial post we learned how to set up a fingerprint sensor and how to use it with our arduino you can use this knowledge to control a.

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. Therefore there is one master arduino which controls the servo oled and fingerprint sensor while a slave arduino controls the leds. It uses a keypad and fingerprint scanner to grant a user access by controlling an electric door s. Using a little arduino programming the fingerprint reader checks to see if you have access and if approved the arduino mega development board unlocks the door using a micro servomotor.

But it is not only expensive and it is also very troublesome to install. You can add a solenoid instead of this led and make a fingerprint door lock which could be a brief tutorial for the future but for this tutorial led indication is our eureka. The diy biometric lock is also equipped with three push buttons and a 16 2 lcd display. How to make fingerprint door lock at home from this tutorial you can make awesome fingerprint sensored locking system for your door.

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. After installing the apk and connecting the hardware as per the circuit diagram connect the arduino to the laptop and upload the code remove the tx rx pins before uploading the code. Using pwm the master can send different voltages to the slave. They are connected through a single wire that goes from a pwm pulse width modulation enabled pin on the master to an analog pin on the slave.

The project arduino fingerprint sensor lock is simply fabricated around arduino board.
