Final major project introduction

 This system aims to eliminate proxy attendance in a classroom by using biometric fingerprint recognition, integrated with Arduino technology. Traditionally, proxy attendance has been a common issue in classes, where students mark attendance for others who are not present. The proposed solution involves the use of biometric fingerprint scanning to accurately record attendance.

For instance, a class scheduled at 4 PM will have its attendance data pre-stored online in a database, which the Arduino will sync with. When a student enters the classroom, they will scan their fingerprint using the biometric system. Upon scanning, the system will display the student's name and roll number on an LCD screen. If a student attempts to mark attendance more than once, the system will display a message indicating that they have already been marked present.

Additionally, if a student who is not registered in the system tries to mark attendance, the LCD will show a "Not Registered" message. To further prevent fraud, if a student from a different class attempts to mark their attendance, the system will display a message stating that they do not belong to this class. This mechanism ensures that only the correct students are able to mark their attendance, and proxy attendance is effectively eliminated.

Furthermore, the system includes an "attendance lock" feature that can only be accessed and managed by the professor. This ensures that no unauthorized changes can be made to the attendance data once it has been recorded. All attendance records are stored in a secure online database, which can be accessed by the professor or relevant authorities for verification.

The key benefits of this system include the complete elimination of proxy attendance and the automatic synchronization of attendance data, providing real-time tracking and ensuring transparency in the attendance process.

  What's Happening in the Code Initialization: Sets up I2C communication on GPIO21 (SDA) and GPIO22 (SCL) Scans for connected devices to verify connections Initializes the LCD and turns on backlight Checks if RTC is working and sets time if it lost power Main Loop: Every 500 milliseconds, reads current time from RTC Converts UTC time to UK time (automatically handles GMT/BST switching) Updates LCD only when values change to reduce flicker Prints to serial monitor for debugging UK Time Zone Logic The code automatically figures out if Britain is in GMT or BST: BST starts on the last Sunday of March at 1:00 AM UTC BST ends on the last Sunday of October at 1:00 AM UTC Outside these dates, it displays GMT Display Format Line 1: Shows time in HH:MM:SS format (centered) Line 2: Shows BST/GMT indicator with date (e.g., "BST Mar 15 2024") Key Features Real-time accuracy using DS3231's temperature-compensated crystal Automatic  timezone  adjustment for UK Effici...
