Overview / Usage

In this project, we are going to design a Fingerprint Sensor Based

Biometric Attendance System using Arduino. Simply we will be

interfacing fingerprint sensor with Arduino, LCD Display & RTC

Module to design the desired project. In this project, we used

the fingerprint Module and Arduino to take and keep attendance

data and records.

Biometric Attendance systems are commonly used systems to

mark the presence in offices and schools. This project has a wide

application in school, college, business organization, offices where

marking of attendance is required accurately with time. By using

the fingerprint sensor, the system will become more secure for the

users

Methodology / Approach

The working of the Fingerprint Sensor Based Biometric Attendance System.

In this project, we have used a DS3231 RTC Module for time & date display.

We used 1 LED for power indication, 1 buzzer for different function indication.

We have interfaced 16*2 LCD which displays everything whenever the finger

is placed or removed, or registering attendance or downloading data.

We have used 4 push buttons which are used to control the entire system.

The functions of each button are:

1. Register/Back Button – Used for enrolling new fingerprint as well as

reversing the back process or going back.

1. Delete/OK Button – This Button is used for deleting the earlier stored

fingerprint system as well as granting access as an OK selection.

1. Forward Button – Used for moving forward while selecting the memory

location for storing or deleting fingerprints.

1. Reverse Button – Used for moving backward while selecting memory

location for storing or deleting fingerprin
