Overview & Motivation

To design and build a physical IoT solution that logs unique user card keys and displays status instantly.

Manual student or staff attendance roll calls are slow, error-prone, and logistically tedious to digitize.

Wired and coded an Arduino Uno controller reading MFRC522 RFID signals and outputting logs to a 16x2 I2C LCD screen.

Built a fully functional sensor circuit delivering instantaneous RFID scanning, validation, and visual log outputs.
