Abstract: This project describes the designing of an automatic vending machine using Finite State Machine as this technique has more advantages compared to previous ones used for vending machine design. We have stated the suitable FPGA board for this automated dispenser. Microprocessor and microcontroller devices have very small random access memory And there are many other issue like high power Consumption, Low reprogramming ability and low Operating frequency But FPGA based technology is avoided from these issues.In supporting this requirement, the manipulation of vending machine is identified as a tool to promote modern and healthy living style, besides to simplify the cooking process.Nowadays with the increasing quantity of waste generated and restricted lowland house for waste disposal The vending machine accepts plastics as inputs in any sequence and delivers products when required weight of plastics is deposited and gives the food products. FPGA based vending machine in less time consuming, uses less power and also rapid proto typing. The FPGA based machine is likewise more adaptable, programmable and can be re-customized. Wastages of plastics are inserted into the machines. The machine accepts that plastics and items will dropped on the tray. The efficient algorithm for this automat is implemented in Verilog HDL and simulated using Xilinx ISE simulator tool.
