Fingerprint Door Lock System Using Arduino Code

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.

Fingerprint door lock system using arduino code.

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. 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.

Now i need to store my fingerprint to crowduino to let it open the door as i press the fingerprint. 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 diy biometric lock is also equipped with three push buttons and a 16 2 lcd display. Just place the finger and open the door.

Some examples are pir based security system rfid based security system digital lock system bio matrix systems electronics code lock. In this project we will learn how to make password based door lock security system using arduino keypad. 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. I use the following modules.

Finger print is considered one of the safest key to lock. A servo with enough torque. It will open your door only when the right password is entered. Glue or anything that can be used to fix these modules 5.

It uses a keypad and fingerprint scanner to grant a user access by controlling an electric door s. 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 project arduino fingerprint sensor lock is simply fabricated around arduino board. It is also faster to use than typing the code of the keypad door lock.

In this post we will interface a fingerprint sensor module with arduino and will build a fingerprint based biometric security system with door locking. Now we have a functioning core of a system. As thefts are increasing day by day security is becoming a major concern nowadays. Arduino fingerprint door lock with keypad and lcd.

Open the arduino ide open the file sketchbook enroll you will see the enroll code that function as a fingerprint registration. 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. This is a security door lock with fingerprint sensor.
