Fingerprint Door Lock Using Arduino

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

Fingerprint door lock using arduino. Make sure you get a fingerprint sensor that works with the arduino through the serial communication. 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. 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. After learning arduino for 2 weeks i decided to diy a fingerprint lock with arduino.

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. The project arduino fingerprint sensor lock is simply fabricated around arduino board. The diy biometric lock is also equipped with three push buttons and a 16 2 lcd display. 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.

Using pwm the master can send different voltages to the slave. Arduino fingerprint door lock with keypad and lcd. After that turn on the bluetooth of your phone and then pair the bluetooth module with your phone. How to make fingerprint door lock at home from this tutorial you can make awesome fingerprint sensored locking system for your door.

It uses a keypad and fingerprint scanner to grant a user access by controlling an electric door s. This is a security door lock with fingerprint sensor. 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. But it is not only expensive and it is also very troublesome to install.

Therefore there is one master arduino which controls the servo oled and fingerprint sensor while a slave arduino controls the leds. Testing the fingerprint door lock using arduino project. First of all connect the fingerprint sensor to the arduino uno. You need adafruit finge.

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.
