Fingerprint Sensor Door Lock Arduino

In this post we will interface a fingerprint sensor module with arduino and will build a fingerprint based biometric security system with door locking.

Fingerprint sensor door lock arduino.

Go ahead and install this. Open the arduino ide open the file sketchbook enroll you will see the enroll code that function as a fingerprint registration. The project arduino fingerprint sensor lock is simply fabricated around arduino board. 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.

Finger print is considered one of the safest key to lock or unlock any system as it can recognize any person uniquely and can t be copied easily. In this tutorial post we learnt how to set up a fingerprint sensor and how to use it with our arduino you can use this knowledge to control a door lock and led or any apparatus that you want to control. When the library manager loads search for fingerprint and the first result should be the adafruit fingerprint sensor library. So if you made similar project do let us know by posting your work under i made it section.

In this tutorial i m going to show you how to build a door lock that uses a fingerprint sensor and an arduino uno. 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. 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. With the library installed it s time to create a new arduino project.

Whether from the inside or outside whenever the door is locked the leds turn red and whenever the door is unlocked they turn green. How to make fingerprint door lock at home from this tutorial you can make awesome fingerprint sensored locking system for your door. You need adafruit finge. From inside you can press the reset pin on the arduino to lock or unlock the door.

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.
