Fingerprint Door Lock Using Arduino Code

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.

Fingerprint door lock using arduino code.

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. As thefts are increasing day by day security is becoming a major concern nowadays. The project arduino fingerprint sensor lock is simply fabricated around arduino board. Some examples are pir based security system rfid based security system digital lock system bio matrix systems electronics code lock.

First of all connect the fingerprint sensor to the arduino uno. Finger print is considered one of the safest key to lock. Hello and welcome to this project actually it includes two projects but they re pretty much the same it s a door lock system based on an arduino uno board fpm10a optical fingerprint sensor and a lcd i c screen but for the other version we inclu. Code for master fingerprint sensor one page 2 2c c.

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. After that turn on the bluetooth of your phone and then pair the bluetooth module with your phone. Testing the fingerprint door lock using arduino project. So a digital code lock can secure your home or locker easily.

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. Whether from the inside or outside whenever the door is locked the leds turn red and whenever the door is unlocked they turn green. Make sure you get a fingerprint sensor that works with the arduino through the serial communication. Arduino fingerprint door lock.

In this post we will interface a fingerprint sensor module with arduino and will build a fingerprint based biometric security system with door locking. Just place the finger and open the door. Also it is almost impossible to trick this door lock since a fingerprint is difficult to copy so with a metal case instead of plastic this would be a very secure door lock. It will open your door only when the right password is entered.

Now i need to store my fingerprint to crowduino to let it open the door as i press the fingerprint. 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. Open the arduino ide open the file sketchbook enroll you will see the enroll code that function as a fingerprint registration. 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.
