Fingerprint Door Lock Using Arduino

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.

Fingerprint door lock using arduino.

Testing the fingerprint door lock using arduino project. The project arduino fingerprint sensor lock is simply fabricated around arduino board. First of all connect the fingerprint sensor to the arduino uno. 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 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. 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. It uses a keypad and fingerprint scanner to grant a user access by controlling an electric door s. I hope to find a cheap way and do need not change my locks.

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. This is a security door lock with fingerprint sensor. Arduino fingerprint door lock with keypad and lcd. You need adafruit finge.

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. Therefore there is one master arduino which controls the servo oled and fingerprint sensor while a slave arduino controls the leds. A fingerprint lock would be help for me and there are plenty of these kinds of locks on the market as the picture above. Make sure you get a fingerprint sensor that works with the arduino through the serial communication.

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