Overview Arduino Fingerprint Door Lock In This Project We Are Going Overview: arduino fingerprint door lock. in this project, we are going to build a fingerprint door lock using arduino nano with bluetooth module, solenoid lock, and android smartphone. an android application is designed, which scans and verifies the fingerprint and sends confirmation data to arduino through bluetooth serial communication. First of all, connect the fingerprint sensor to the arduino uno. make sure you get a fingerprint sensor that works with the arduino through the serial communication. 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. for this.
Diy Fingerprint Door Lock System Arduino Project Hub Hardware description of fingerprint based door lock system arduino. arduino is an open source electronic platform based on easy to use hardware and software. arduino boards are able to read inputs – light on sensor, a finger on a button, or a twitter message – and turn it into an output – activating a motor, turning on an led, publishing some thing online. Schematic diagram – fingerprint door lock security systems using arduino & lcd. connect the fingerprint sensor to the arduino board as follows: circuit diagram. vcc pin to 5v pin on the arduino. gnd pin to gnd pin on the arduino. tx pin to digital pin d2 on the arduino. rx pin to digital pin d3 on the arduino. Copy the provided code to the arduino ide and install the necessary libraries. upload the code to the arduino board and open the serial monitor (baud rate: 9600). if the fingerprint sensor is connected successfully, the lcd will display “ fingerprint sensor connected. place your finger on the sensor to start the scan. Step 1: tools. the hardware needed for this project are: arduino board, here i'm using an uno. adafruit fpm10a optical fingerprint sensor. lcd i²c screen. and for the second version of the project you'll need a keypad, here i'm using 4x4. and don't forget about your door lock system, i used the one in the picture (10 bucks from chinese.

Step 7: testing the project. to test if the project is working properly, plug the arduino mega into a power source. the oled screen should turn on and display "fingerprint smart door lock" after that, the screen will display a message asking you to scan a finger to set it as a master finger. once you have scanned your finger, it will be saved. From outside the door, a person is greeted with a fingerprint sensor and a display saying if the door is locked or unlocked. whenever the system is at rest, the rgb leds are randomly fading through 16.8 million colors. if an incorrect finger is placed, the leds angrily flash red and the oled displays “incorrect finger”.
