RFID Attendance System.
Classroom attendance tracked with RFID cards, from Arduino hardware to a real-time web dashboard.
About
Group project: an RFID-RC522 reader on Arduino Uno captures card scans, with LED and buzzer feedback on every tap.
Scans stream over serial to a Node.js and Express backend that persists attendance in MongoDB via Mongoose. The React frontend shows the present-student list updating in real time as cards are swiped.
Shipped with a full wiring schematic and setup guide, from library install to running both servers.
