Arduino uno fingerprint door 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. I got my fingerprint scanner and lcd to work but my door lock just doesnt want to work. From outside the door a person is greeted with a fingerprint sensor and a display saying if the door is locked or unlocked. I hope to find a cheap way and do need not change my locks.

First of all connect the fingerprint sensor to the arduino uno. Arduino uno fingerprint scanner door lock read 993 times previous topic next topic. After learning arduino for 2 weeks i decided to diy a fingerprint lock with arduino. It works when i dont.

I am using fingerprint module r307 and lcd together. I really need help with this one. Define servopin 9 define pin number to which servo motor is connected define durationtime 3000 define the time it remains in the open position of the door lock miliseconds define servomin 0 open position define servomax 90 closed position. The diy biometric lock is also equipped with three push buttons and a 16 2 lcd display.

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. 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. Arduino uno fingerprint scanner door lock. A fingerprint lock would be help for me and there are plenty of these kinds of locks on the market as the picture above.

But it is not only expensive and it is also very troublesome to install. This is a security door lock with fingerprint sensor. Having them run off battery enables the system to keep running even during a black out. The whole system is run with dual arduino unos and powered by portable battery packs.

Make sure you get a fingerprint sensor that works with the arduino through the serial communication. Arduino fingerprint door lock. 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.
