How Attendance works in this Fingerprint Attendance System Project: Now LCD will let you know that fingerprint has been deleted successfully. Now user needs to select ID and press OK key (same DEL key). Once delete key is pressed LCD will ask to select ID that need to be deleted. Now if the user wants to remove or delete any of the stored ID or fingerprint, then he/she need to press DEL key. Now the user will be registered and he/she can feed attendance by putting their finger over fingerprint module.By the same method, all the users will be registered into the system. Now user needs to put his finger again and module takes an image and convert it into templates and stores it by selected ID into the finger print module’s memory. Now the LCD will say to remove finger from fingerprint module, and again ask to place finger again. Now user needs to place his finger over finger print module and then the module takes finger image. Now LCD will ask to place finger over the fingerprint module. After selecting ID, user needs to press OK key (DEL key). So now user needs to enter ID by using UP/DOWN keys. To do this, user need to press ENROLL key and then LCD asks for entering ID for the fingerprint to save it in memory by ID name. First of all, the user needs to enroll fingerprints of the user with the help of push buttons. 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.
#HARDWARE FINGERPRINT BLOCKER SERIAL#
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.

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.
