User may download the attendance data by pressing and holding key 4. Time and date are running continuously in the system, so MicrocontrollerВ can take time and date whenever a true user places his finger over fingerprint sensor and then save them in the EEPROM at the allotted slot of memory. If fingerprint ID is detected then LCD will show Attendance registered and in the same time buzzer will beep once.ДЄlong with the fingerprint module,В we have also used an RTC module for Time and date data. Whenever user placeВ his finger over fingerprint module then fingerprint module captures finger image, and search if any ID is associated with this fingerprint inВ the system.

And PD7 is used as soft UART Tx pin for getting the current time. RTC module is connected at I2Cpin PC0 SCL and PC1 SDA. A 16x2 LCD is configured in 4-bit modeВ and its RS, RW, EN, D4, D5, D6, and D7 are directly connected at pin PB0, PB1, PB2, PB4, PB5, PB6, PB7 of microcontroller. 5v supply is used for powering the whole circuit by using LM7805 voltage regulator which is powered by 12v dc adaptor.

Fingerprint moduleвЂ™s Rx and Tx directly connected at Serial pin PD1 and PD3 of microcontroller. And a LED is connected at pin PC2 of microcontroller with respect to ground through a 1k resistor.

The push or membrane button is used for enrolling, deleting, selecting IDs for attendance, a buzzer is used for indication and a 16x2 LCD to instruct user on how to use the machine.ДЄs shown in the circuit diagram, push or membrane buttons are directly connected to pin PA2 (ENROL key 1), PA3(DEL key 2), PA0(UP key 3), PA1(DOWN key 4) of microcontroller with respect to the ground or PA4. It hasВ Atmega32 microcontroller for controlling all the process of the project. The complete circuit diagram for fingerprint based attendance system project, is shown below. You can also check out these other finger print sensor projects, where we have built finger print sensor security system and fingerprint sensor voting machine. All the process is commanded by the microcontroller, like taking an image of fingerвЂ™s print convert it into templates and storing as ID etc. And key 2 is also used for reset or delete data from EEPROM of microcontroller.ДЇingerprint sensor module captures fingerвЂ™s print image and then converts it into the equivalent template and saves them into its memory as per selected ID by microcontroller. Now user need to press key 1 (this time this key behave like OK) to proceed with selected ID. Similarly, key 2 has double function, like when user enrolls new finger, then he/she need to select finger-print ID by using another two keys namely 3 and 4. So when the user wants to enroll a new finger, then he/she need to press key 1 then LCD asks him/her to place a finger on fingerprint sensor two times then it asks for an employee ID. Key 1 is used for enrollment of a new person into the system. Here we are using 4 push buttons to enroll, Delete, Increment and Decrement finger-print data. In this fingerprint attendance system circuit, we have usedВ the Fingerprint Sensor moduleВ to authenticate a person or employeeвЂ™s identity by taking their finger-print input inВ the system. Following sections explains technical details of making a fingerprint-based Biometric Attendance System using AVR. By using fingerprint sensor, the system will become more secure for the users. In this project, we have used fingerprint Module and AVR(atmega32) to register attendance. This system will be more reliable and efficient since it would save time and avoid dodgers.ДЇingerprint attendance systems are already readily available directly from the market, but what is more fun than building one? We have also built a wide variety of Attendance Systems earlier from a simple RFID based Attendance system to an IoT based biometric Attendance system using Arduino and Raspberry Pi.

To keep up with the phase, in this project we will build a Bio-metric Attendance system using AVR microcontrollers to replace the manual procedure of taking attendance. Today, from bridge toll collectors to check-out cashiers everything around us is being replaced by machines to get the work done easier and more efficient. Today, in the world where AI, Machine learning, Chat bots, Smart Speakers, Robots etc are actively progressing, this synergy between humans and robots is only set to increase. According to researchers from Pen state University, humans are more likely to trust machines over people, which is likely evident from us revealing our ATM pin to a machine so easily.
