A servo with enough torque.
Fingerprint door lock system using arduino code.
Just place the finger and open the door.
In this project we will learn how to make password based door lock security system using arduino keypad.
It will open your door only when the right password is entered.
It uses a keypad and fingerprint scanner to grant a user access by controlling an electric door s.
5v usb power supply or 9v dc jack power supply.
Crowduino this is an arduino compatible microcontroller boards i use it because it is cheap enough and has some upgrading on the design such as the reset button on the side.
In this post we will interface a fingerprint sensor module with arduino and will build a fingerprint based biometric security system with door locking.
Therefore i installed an optical fingerprint sensor on the outside of the door that can also toggle the locked versus unlocked position of the servo.
The project arduino fingerprint sensor lock is simply fabricated around arduino board.
Now i need to store my fingerprint to crowduino to let it open the door as i press the fingerprint.
Also it is almost impossible to trick this door lock since a fingerprint is difficult to copy so with a metal case instead of plastic this would be a very secure door lock.
I use the following modules.
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.
Now we have a functioning core of a system.
Some examples are pir based security system rfid based security system digital lock system bio matrix systems electronics code lock.
To enhance the system i ve also installed a small oled display on the outside of the door to show the system s status i e.
As thefts are increasing day by day security is becoming a major concern nowadays.
It is also faster to use than typing the code of the keypad door lock.
The diy biometric lock is also equipped with three push buttons and a 16 2 lcd display.
This is a security door lock with fingerprint sensor.
Make sure you get a fingerprint sensor that works with the arduino through the serial communication.
First of all connect the fingerprint sensor to the arduino uno.
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.
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.
Arduino fingerprint door lock with keypad and lcd.
So a digital code lock can secure your home or locker easily.
Open the arduino ide open the file sketchbook enroll you will see the enroll code that function as a fingerprint registration.
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.
