First of all connect the fingerprint sensor to the arduino uno.
Fingerprint door lock system using arduino code.
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.
The electromagnetic lock em lock is also known as magnetic lock or maglock.
After installing the apk and connecting the hardware as per the circuit diagram connect the arduino to the laptop and upload the code remove the tx rx pins before uploading the code.
It will open your door only when the right password is entered.
Testing the fingerprint door lock using arduino 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.
In this post we will interface a fingerprint sensor module with arduino and will build a fingerprint based biometric security system with door locking.
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.
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.
In the future there could be many more applications like fingerprint based driving licences bank accounts operation and so on.
We will learn how electromagnetic lock works how to connect electromagnetic lock to arduino how to program arduino step by step.
This simple fingerprint door unlock project using arduino can be very useful for door security forensics crime investigation personal identification attendance system and much more.
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.
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.
Finger print is considered one of the safest key to lock.
The detail instruction code wiring diagram video tutorial line by line code explanation are provided to help you quickly get started with arduino.
Now we have a functioning core of a system.
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 that turn on the bluetooth of your phone and then pair the bluetooth module with your phone.
It uses a keypad and fingerprint scanner to grant a user access by controlling an electric door s.
Open the arduino ide open the file sketchbook enroll you will see the enroll code that function as a fingerprint registration.
Some examples are pir based security system rfid based security system digital lock system bio matrix systems electronics code lock.
So a digital code lock can secure your home or locker easily.
