Vending machine that dispense items like as snacks, coffee, beverages, lottery ticket,
consumer products automatically when a customer insert a coin or token are increasing rapidly
in metropolitan’s cities due to contemporary and fast life style requiring excellent quality
products. This paper give the details account of the designing and implementation of a multi
select state vending machine using State Machine with which users can select the product and
insert the desired token for respective products to dispense the Integrated Circuit (IC) or it will
return the inserted token if wrong token is inserted for each Integrated Circuit (IC). We choose
FPGA for this vending machine since FPGA based vending give quicker response and absorbed
less power and reprogrammed anytime as compared to CMOS vending machine. The intended
design is implemented in VHDL and simulated using Xilinx VIVADO 2019.1 and it’s implemented
on FPGA basy -3 Artix 7 series FPGA (xc7a200tfbg676) development board. Synthesis results and
FPGA experimental results are shown in this paper.
