Problem Statement:

Manual attendance tracking in engineering colleges and office access control is prone to human error, proxy attendance, time delays, and tedious paperwork management.

Proposed Technical Solution:

The Arduino Smart Fan Speed Controller provides an automated hardware-software system. Utilizing high-frequency 13.56MHz / 860-960MHz UHF RFID readers connected to an ESP32 Wi-Fi microcontroller, card scans are instantly validated, displayed on an OLED screen, and uploaded via encrypted MQTT protocol to a central database.

Key Technical Features:

Instant contactless RFID card scanning under 200ms latency.
Onboard Wi-Fi and Bluetooth BLE connectivity for seamless cloud sync.
Real-time timestamp logging with offline EEPROM memory backup.
Audio-visual feedback via piezobuzzer and status LEDs.
Web-based admin portal for managing student/employee records.
