Finger print is considered one of the safest key to lock.
Fingerprint door lock system using arduino code.
In this post we will interface a fingerprint sensor module with arduino and will build a fingerprint based biometric security system with door locking.
Just place the finger and open the door.
Arduino fingerprint door lock with keypad and lcd.
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.
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.
After downloading the sketch enrollto crowduino open the serial monitor and set the baud rate to 38400 you will see the outputs from the serial monitor to.
The diy biometric lock is also equipped with three push buttons and a 16 2 lcd display.
It will open your door only when the right password is entered.
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.
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.
In this project we will learn how to make password based door lock security system using arduino keypad.
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.
A servo with enough torque.
I use the following modules.
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.
This is a security door lock with fingerprint sensor.
Glue or anything that can be used to fix these modules 5.
As thefts are increasing day by day security is becoming a major concern nowadays.
5v usb power supply or 9v dc jack power supply.
Some examples are pir based security system rfid based security system digital lock system bio matrix systems electronics code lock.
Now we have a functioning core of a system.
The project arduino fingerprint sensor lock is simply fabricated around arduino board.
Open the arduino ide open the file sketchbook enroll you will see the enroll code that function as a fingerprint registration.
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.
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.
