Fingerprint Door Lock Using Arduino Circuit Diagram

This is a really awesome projec.

Fingerprint door lock using arduino circuit diagram.

It uses a keypad and fingerprint scanner to grant a user access by controlling an electric door s. Code and circuit diagram for fingerprint sensing door locking system july 3 2019 january 22 2020 admin 0 comments. I am using fingerprint module r307 and lcd together. 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.

Introductionthe fingerprint door lock as the name suggests is an electronic door lock that can be installed on almost any access point in your house. Make sure you get a fingerprint sensor that works with the arduino through the serial communication. It will open your door only when the right password is entered. For connecting the keypad with the arduino we are using both analog and digital pins.

First of all we will make the connection to the 4 4 keypad. In this project we will learn how to make password based door lock security system using arduino keypad. Circuit diagram of the fingerprint door unlock system the brain of the circuit is arduino uno mcu board board1. As thefts are increasing day by day security is becoming a major concern nowadays.

We used analog pins since we need more that 14 digitals pins for this project. 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. Code and circuit diagram for bluetooth rc car using arduino. 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.

First of all connect the fingerprint sensor to the arduino uno. So a digital code lock can secure your home or locker easily. How to make electric fingerprint door lock at home using adafruit fingerprint sensor electric door lock arduino uno. 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.

Circuit diagram explanation digital door lock using arduino circuit diagram. The project arduino fingerprint sensor lock is simply fabricated around arduino board. In this video i show you how to use the fingerprint scanner for a door lock using arduino uno.
