Arduino Uno Fingerprint Door Lock

It works when i dont.

Arduino uno fingerprint door lock.

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. After learning arduino for 2 weeks i decided to diy a fingerprint lock with arduino.

First of all connect the fingerprint sensor to the arduino uno. The whole system is run with dual arduino unos and powered by portable battery packs. This is a security door lock with fingerprint sensor. 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.

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. The diy biometric lock is also equipped with three push buttons and a 16 2 lcd display. I got my fingerprint scanner and lcd to work but my door lock just doesnt want to work. Arduino uno fingerprint scanner door lock.

I am using fingerprint module r307 and lcd together. Adafruit fingerprint finger adafruit fingerprint myserial. In that i am using 2 3 digital pins of arduino for data transfer to the fingerprint i tried other pin configurations for this but it didn t work but as i am connecting lcd it also requires same 2 3 digital pins of arduino and it is not possible for me to use 2 and 3 pins of arduino for both lcd and fingerprint sensor for data transfer. 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.

But it is not only expensive and it is also very troublesome to install. 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.
