This document discusses the development of a smart vending machine with an embedded system. It outlines requirements to control 60 motors, integrate RFID and barcode scanning, and allow for easy communication. It then details the implementation of a function block diagram and circuits to control motors, communicate via UART, USB, and address difficulties with limit switch noise, finding a stable motor control algorithm, infrared sensor noise, and choosing the wrong RFID module. A video demo of the final product is also mentioned.
