Fingerprint Door Lock System Using Arduino

Open the arduino ide open the file sketchbook enroll you will see the enroll code that function as a fingerprint registration.

Fingerprint door lock system using arduino.

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. To enhance the system i ve also installed a small oled display on the outside of the door to show the system s status i e. Now we have a functioning core of a system. Testing the fingerprint door lock using arduino project 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.

This door lock will only open the door when the user scans the right fingerprint that is recorded on the system but the door will remained close upon entering the wrong fingerprint. Some examples are pir based security system rfid based security system digital lock system bio matrix systems electronics code lock. Arduino fingerprint door lock with keypad and lcd. As thefts are increasing day by day security is becoming a major concern nowadays.

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. In this project we will learn how to make password based door lock security system using arduino keypad. Now i need to store my fingerprint to crowduino to let it open the door as i press the fingerprint. In this post we will interface a fingerprint sensor module with arduino and will build a fingerprint based biometric security system with door locking.

It uses a keypad and fingerprint scanner to grant a user access by controlling an electric door s. 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. In this tutorial i m going to show you how to build a door lock that uses a fingerprint sensor and an arduino uno. Finger print is considered one of the safest key to lock.

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. The project arduino fingerprint sensor lock is simply fabricated around arduino board. Therefore i installed an optical fingerprint sensor on the outside of the door that can also toggle the locked versus unlocked position of the servo.
