Fingerprint Door Lock Using Arduino

First of all connect the fingerprint sensor to the arduino uno.

Fingerprint door lock using arduino.

Arduino fingerprint door lock with keypad and lcd. 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. Testing the fingerprint door lock using arduino project. You need adafruit finge.

Using pwm the master can send different voltages to the slave. 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. Therefore there is one master arduino which controls the servo oled and fingerprint sensor while a slave arduino controls the leds. 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.

A fingerprint lock would be help for me and there are plenty of these kinds of locks on the market as the picture above. 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. The diy biometric lock is also equipped with three push buttons and a 16 2 lcd display. The project arduino fingerprint sensor lock is simply fabricated around arduino board.

How to make fingerprint door lock at home from this tutorial you can make awesome fingerprint sensored locking system for your door. 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. 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.

I hope to find a cheap way and do need not change my locks. 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. This is a security door lock with fingerprint sensor. After that turn on the bluetooth of your phone and then pair the bluetooth module with your phone.

After learning arduino for 2 weeks i decided to diy a fingerprint lock with arduino.
