However since the arduino uno only has one hardware serial port you need to use a software serial port using pins 2 and 3 to talk to the fingerprint module the hardware serial port is reserved for pc communication.
Arduino uno fingerprint door lock 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.
From outside the door a person is greeted with a fingerprint sensor and a display saying if the door is locked or unlocked.
You can directly upload the code but it is recommended to read the below paragraphs to understand how the code works.
In today s tutorial we will learn to use a fingerprint sensor with any arduino board and we will possibly make a simple practical example of this sensor so let s learn together.
Soldering wire optional 1.
In this video i show you how to use the fingerprint scanner for a door lock using arduino uno.
For making fingerprint door lock you need arduino uno adafru.
Having them run off battery enables the system to keep running even during a black out.
In this tutorial i m going to show you how to build a door lock that uses a fingerprint sensor and an arduino uno.
The detail instruction code wiring diagram video tutorial line by line code explanation are provided to help you quickly get started with arduino.
Hello guys welcome back to another arduino tutorial.
Finger print is considered one of the safest key to lock.
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.
Open the arduino ide open the file sketchbook enroll you will see the enroll code that function as a fingerprint registration.
And make a fingerprint door lock which could be a brief tutorial for the future but for this tutorial led indication is our eureka.
Also it is important to make sure you have added the following keypad library to your arduino ide to compile the code successfully.
Some examples are pir based security system rfid based security system digital lock system bio matrix systems electronics code lock.
The complete arduino door lock code can be found at the bottom of this page.
Upload the main code.
The electromagnetic lock em lock is also known as magnetic lock or maglock.
Now i need to store my fingerprint to crowduino to let it open the door as i press the fingerprint.
