Description:

Fingerprint Based Biometric Attendance System– This Tutorial is about the Arduino based Fingerprint attendance which is also called a Biometric attendance system. The students are marked Present, Late, and absent depending on the time, The attendance application will be designed in Microsoft visual basic 2010 express edition and the Arduino programming will be done in the Arduino IDE “C Language”.

Another more advanced version of the student’s attendance system which is based on Firebase Database, RFID, GSM, and Nodemcu ESP8266.



 A few days backs I posted a tutorial on the fingerprint module in which I covered all the basics, including its interfacing with Arduino, and how to enroll fingers. In that tutorial, I already enrolled three fingers, so I will be using the same fingers to represent student1, student 2, and student3. I highly recommend first you should watch this tutorial.

This is a very basic student’s attendance system without a database, while in the upcoming tutorial I will modify this project and include a database, then each student record can be edited, checked, deleted, or updated.

For the complete step by step explanation, you can watch Video Tutorial given at the end of this article.

Fingerprint Module that we will be using with the Arduino:

This is the fingerprint module that we will be using today with the Arduino. It has a total of six wires. While some fingerprint modules have 4 wires, but their use is exactly the same. As you can this module has six wires, but we will be using only 4 wires, Red, green, white and black.

We don’t need the yellow and blue wires.

connect the red wire with the Arduino’s 5v.

Connect the black wire of the fingerprint module with the Arduino’s ground.

Connect the green wire with pin 4 of the Arduino and connect the white wire with pin5 of the Arduino. so now our interfacing is completed.

Now it’s time to enroll fingers. For Fingers enrolling watch my Previous Tutorial “Click Here

Circuit Diagram:

As you can see in the circuit Diagram a 433Mhz RF transmitter is also used which will be used in the future project. In this tutorial, you can neglect this RF Transmitter. The Finger Print module is connected with the Arduino’s pin number 4 and Pin number 5. The 5v pin of the Finger Print Module will be connected with the Arduino 5v pin and ground of the Finger Print module will be connected with the ground of Arduino.


fingerprint attendance Programming:

This project is based on two programs, Arduino programming, and Vb.net Programming. Before, you start the programming, first of all, make sure that you download the necessary libraries.
