Overview
An automated vending machine built from scratch, supporting both mobile banking and RFID card payments — a cashless campus cafe in a box.
Key features:
Key features:
- Dual payment paths: RFID card tap and mobile banking confirmation
- Servo-driven dispensing mechanism for product delivery
- SONAR-based detection to confirm successful dispensing
- Fully self-contained embedded system on Arduino
My role
Hardware and firmware developer.
- Designed the circuit integrating RFID reader, SONAR sensor, and servo actuators.
- Wrote the Arduino firmware coordinating payment verification and dispensing.
- Handled the payment-state logic and error recovery for failed dispenses.
