Efficient Automatic Food Ordering System using FPGA and ZigBee

This paper presents a new concept of automatic food ordering system using low power FPGA board. Proposed design contains one transmitter section and one receiver section. At the transmitter section, menu of food items is listed on the touch screen module located on the customer table. It is driven by Nexsys4 DDR FPGA board along with Zigbee module and keypad. A display module interfaced with another FPGA board and Zigbee receiver module is housed on the top of table of supervisor of the restaurant. To improve signal to noise ratio, we have used wireless system. Increasing need of reducing human efforts in this era and low power constraint in designing were the motivational challenges behind this proposed design.
