FPGA based Vending Machine For Logical Gates

Recently we have seen many Vending machines dispense things like toys, chocolates, shakes, snacks, lottery tickets, etc. Vending machines automatically dispense the different products when a consumer puts a currency or colored or different size token. The requirements for modern vending machines are increasing rapidly due to their ease of use. This research work intends to design a vending machine to sell eight different integrated circuits (ICs). Users can select the desired product and quantity of the product while inserting the currency. The proposed model also shows the available stock and total amount for the entered product. Here, FPGA is used to design the proposed Vending Machine (VM) as FPGAs are more flexible than embedded systems. The proposed vending machine is mainly used to vend the logical gates. It has better advantages as the quantity and amount can be entered according to the user requirements. The developed vending machine can be used in schools, research laboratories etc. FPGAs can be reprogrammed any number of times, consume less power and work faster than CMOS based Vending machines. Finally, the proposed design is simulated using Xilinx 14.7 and then implemented using FPGA kit artic 7.
