Fingerprint Door Lock Using Arduino Circuit Diagram

For making fingerprint door lock you need arduino uno adafru.

Fingerprint door lock using arduino circuit diagram.

I am using fingerprint module r307 and lcd together. Code and circuit diagram for bluetooth rc car using arduino. For connecting the keypad with the arduino we are using both analog and digital pins. In this video i show you how to use the fingerprint scanner for a door lock using arduino uno.

Make sure you get a fingerprint sensor that works with the arduino through the serial communication. Circuit diagram explanation digital door lock using arduino circuit diagram. In this project we will learn how to make password based door lock security system using arduino keypad. As thefts are increasing day by day security is becoming a major concern nowadays.

This is a really awesome projec. It will open your door only when the right password is entered. 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. We used analog pins since we need more that 14 digitals pins for this project.

First of all connect the fingerprint sensor to the arduino uno. First of all we will make the connection to the 4 4 keypad. Circuit diagram of the fingerprint door unlock system the brain of the circuit is arduino uno mcu board board1. How to make electric fingerprint door lock at home using adafruit fingerprint sensor electric door lock arduino uno.

Code and circuit diagram for fingerprint sensing door locking system july 3 2019 january 22 2020 admin 0 comments. Code and circuit diagram for smart locking door system using rfid sensor and arduino board. It is based on atmega328 atmega328p and has 14 digital input output i o pins six analogue inputs 32k flash memory 16mhz crystal oscillator a usb connection power jack icsp header and reset button among others. 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.

So a digital code lock can secure your home or locker easily. It uses a keypad and fingerprint scanner to grant a user access by controlling an electric door s. 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.
