Working of this fingerprint attendance system project is fairly simple. Working of Fingerprint Based Attendance System Arduino is the main component of this system it is responsible for control of the whole system. A buzzer is also used for various indications. Here we have added a Yellow LED which indicates that fingerprint module is ready to take an image of the finger. You can check some more projects using fingerprint module:įingerprint based biometric voting machine
All the process is commanded by Arduino like taking an image of finger’s print, convert it into templates and storing as ID etc. And Del key is used for reset or delete data from EEPROM of Arduino.įingerprint sensor module captures finger’s print image and then converts it into the equivalent template and saves them into its memory as per selected ID by Arduino. Now user need to press DEL/OK key (this time this key behave like OK) to proceed with selected ID. Similarly, DEL/OK key also has the same double function like when user enrolls new finger, then he/she need to select finger ID by using another two key namely UP and DOWN.

Besides enroll key is also used to download attendance data over serial monitor. ENROLL key has both enrollment and back function. This time ENROLL key behave as Back key, i.e. Now if at this time user does not want to proceed further then he/she can press ENROLL key again to go back. So when the user wants to enroll new finger then he/she need to press ENROLL key then LCD asks for the ID, where user want to be store the finger print image. ENROLL key is used for enrollment of a new person into the system. Here we are using 4 push buttons to enroll, Delete, UP/Down. First of all, we have included some necessary header file then written macros for different-different purpose.In this fingerprint attendance system circuit, we used Fingerprint Sensor module to authenticate a true person or employee by taking their finger input in the system. Hence we have tried to take descriptive variables to make good readability and understanding.
#PROJECT FINGERPRINT ATTENDANCE SYSTEM CODE#
Code of this project is a little bit lengthy and complex for beginner. Code ExplanationĬomplete code along with the video for this biometric attendance system is given at the end. These two steps are not shown in demonstration video given in the end. Now after some time LCD will show ‘Please wait…’ and then ‘Record Deleted successfully’. User also needs a TTL to USB converter to see the attendance data over serial terminal.Īnd if the user wants to delete all the data then he/she has to press and hold key 2 and then connect power and wait for some time.

And user can see the attendance data over serial monitor, here in this code software UART is programmed at pin PD7-pin20 as Tx to send data to terminal. Connect supply to circuit and wait and after some time, LCD will show ‘Downloading….’. User may download the attendance data by pressing and holding key 4.

Whenever user place his finger over fingerprint module then fingerprint module captures finger image, and search if any ID is associated with this fingerprint in 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 16×2 LCD is configured in 4-bit mode 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 module’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. As 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.
