Design and Simulation of Smart Vending Machine using Microcontroller & FPGA

A vending machine is a machine which provides various items like chock let, chips ,snacks, milk product, snacks, beverages, lottery tickets, consumer products and even gold and gems to customers automatically whenever the customer inserts coin into the machine. Vending machines are very common in most of the countries. In INDIA like Haldiram vending machine is going to be popular. As the world is switch into automation the requirement of vending machine also increases. The FPGA based vending machine is reprogrammed whereas the Embedded based machines needs to change to change the architecture. In this paper of vending machine using Finite State Machine (FSM) Model is proposed with the help of Arduino and GSM module. The sensor used here is temperature. The automatic notification is given to the concern person. The notification gives the real time product dispatch details. VHDL based FSM modelling is the most important part in developing vending machine model as this reduces the required hardware.
