Safe Coin Treasury and Investment System

Designed a coin-based asset lending management system for students, requiring physical coin exchange as collateral for borrowed equipment. Integrated multiple hardware components including an Arduino MEGA 2560, RFID reader, HMI, RTC module, and DHT22 sensor, with a custom 3D-printed PLA enclosure. Developed embedded control logic for user authentication, transaction recording, and environmental monitoring.
