Ragila VV, 2Rosmi Varghese, 3Soorya Rajeev K, 4Shimna PK 1,2,3 UG Student, Dept. of ECE, Vimal Jyothi Engineering College, Kannur, Kerala, India 4 Assistant Professor, Dept of ECE, Vimal Jyothi Engineering College, Kannur, Kerala, India Abstract - Smart Restaurant is concept to realize the automation in restaurants or hotels. In this restaurant the kitchen people can get orders wirelessly from each table. This project consists of two sections one is transmitter section and other is receiver section. In our project we have designed an electronic system to order through wireless communication using an electronic menu card provided on each table. We can select the items through matrix keypad provided. This order details are collected by wireless receiver placed in the kitchen and will display the items in its display. So the kitchen people can supply those items to the customer after preparing it. This will give advantage to avoid the time delay usually experienced during bearer coming, collecting order and finally es to the kitchen manually. Here we use the popular PIC16F877 microcontroller on transmitter side. Liquid Crystal Display are used for the display and the 2.4 GHz open band wireless transceiver modules are used on receiver and transmitter which have range of 30m in indoor.

I. INTRODUCTION a) Background In the last years the restaurant industry has lived through many changes. Anyway, there is an area that was not improved since several decades. While technology is changing the way we do almost everything, menu cards are still mostly untouched - although they have several disadvantages that can be improved significantly by a digital approach. The Digital Menu for Restaurants project aims to improve this situation. Consumers today are adapted to interact with computer systems in many aspects of their day to day life. Sometimes we even prefer them to traditional methods, especially when they help to provide fast and convenient service.
b) Motivation One of the most import areas for the restaurant industry is obviously the customer service. To engage friendly and obliging service staff is most challenging for the majority of restaurant managers. But this is not the only issue in this area. It‟s also hard to motivate people every day, because the customer service in restaurants might become very stressful.

Most of the stress occurs as soon as one customer service member needs to take care of way too many customers at once. That‟s why this project aims to processes needed for the restaurant staff and allow them to focus on the important part – friendly customer service. Adapting this aim for the customers this project increases the overall experience at the next trip to a restaurant. The project is focused on the order process; the kitchen organization and business processes like invoice management. It provides a digital management system for each of these processes.
II. LITERATURE REVIEW Jingjing Wang [1] presented the design and achievement of wireless ordering food system. This paper presented in-depth on the technical operation of 4*4 matrix keyboard to realize data input. N. M. Z. Hashim et-al [2] proposed the smart ordering system via Bluetooth (SOS). It uses a small keyboard to make orders and Bluetooth for transmission. Prof. Sagar Soitkar et-a l[3] presented the touch screen based digital menu ordering system using AVR. This paper dictates the method of low cost, efficient and easy to access the system for digital menu ordering system for restaurants. Asan, N. Badariah et-al [4] developed zigbee–based smart ordering system. The smart ordering system is proposed orders using hand tools used to make an order in a restaurant. Bhanu Siramshetti et-al [5] later on took one step ahead. They further extended the service with zigbee based E-menu ordering system. The development of the E-menu ordering is based on the software-hardware platform on ARM7 (LPC2148), using zigbee for short spectrum radio communication technologies.
III. EXISTING SYSTEM Stress can take place on human finger when used for more than a few minutes at a time. The touch screen can suffer from the problem of fingerprints on the display. The has to sit closer to the screen as compared to the external keyboard. The screen can be covered more by using hand. It poses a great problem for the people who are illiterate [6]-[9].
IV. PROPOSEDSYSTEM Aspiration of the proposed method is to promote a cost effective system which could work in small-scale restaurants that are not willing to invest huge amount of fund in these systems. It provides fast and convenient customer service.

Selection and ordering of items are possible through touch screen. PC display is provided at the kitchen.
a) Block Diagrams i) Transmitter section
Figure 1: Transmitter
ii) Receiver section
i) Transmitter section: An electronic card is provided on each table. It consists of a keypad, MCU, encoder, an RF transmitter and an LCD. MCU displays the food items on the LCD screen with their prices. The customer can select the items by using the INC and DEC key. In order to send the selected items press SEND key. MCU reads data from the keypad and gives corresponding digital output to an encoder. It encodes one of the active inputs to a coded binary output. RF transmitter transmits this coded binary output from the encoder. The RF module, as the name suggests, operates at Radio Frequency. The corresponding frequency range varies between 30 kHz & 300 GHz. Here we are using 2.4GHz band. Transmission through RF is better than IR (infrared) because of many reasons. Firstly, signals through RF can travel through larger distances making it suitable for long range applications and the RF signals can travel even when there is an obstruction between transmitter & receiver. Next, RF transmission is more strong and reliable. ii) Receiver section: The receiver section is placed in the kitchen, it consists of an RF receiver, RF decoder, PC display and visual indicator. RF receiver receives the coded binary data transmitted by the RF transmitter and given to the RF decoder. RF decoder decodes the input and gives four bit digital data to the PC only if the address bit of encoder and decoder matches. Software is installed in PC to display the selected items. Visual indication is interfaced here for intimating the kitchen people.
V. HARDWARE REQUIRMENTS a) Microcontroller Unit PIC microcontroller is the aboriginal RISC ed microcontroller fabricated in CMOS (complementary metal oxide semiconductor) that uses isolated bus for instruction and data allowing simultaneous access of program and data memory. The main favor of CMOS and RISC consolidation is low power consumption resulting in a very small chip size with a small pin count. The essential advantage of CMOS is that it has immunity to noise than other fabrication techniques.

b) Working Principle Digital menu card is a system which is used to overcome the limitation of currently followed system in the restaurant industry. Our digital menu card will provide an automated, fast and accurate care to each customer by allowing customers to transmit orders directly to the kitchen through an electronic card provided at each table.

resistive layer on top of its substrate. One layer has conductive connections along its sides, the other along top and bottom. A voltage is applied to one layer, and sensed by the other. When an object, such as a fingertip or stylus tip, presses down onto the outer surface, the two layers touch to become connected at that point: The then behaves as a pair of voltage dividers, one axis at a time. By rapidly switching between each layer, the position of a pressure on the screen can be read. Resistive touch is used in restaurants, factories and hospitals due to its high resistance to liquids and contaminants. A major benefit of resistive touch technology is its low cost. Additionally, as only sufficient pressure is necessary for the touch to be sensed, they may be used with gloves on, or by using anything rigid as a finger/stylus substitute.
b) Liquid Crystal Display (LCD)
e) RF Module
The HD 44780 is a liquid crystal dot matrix display Module that consists of LCD , LCD control driver, and driver and is capable of providing 16 characters x 2 lines display. It contains a controller, a data RAM and a character generator ROM required for providing display. Data interfacing is in 8bit parallel or 4-bit parallel and data can be written in or read from a microprocessor.
This RF transceiver is having a 30 meter range with onboard antenna of transceiver based on the „Texas Instruments Chip on IC (CC2500)‟. In a typical system, this transceiver will be used together with a microcontroller. It provides extensive hardware for packet handling, data buffering, burst transmissions, clear channel assessment, link quality indication and wake on radio. It can be used in 24002483.5 MHz ISM/SRD band systems. (E.g. RKE-two way Remote Keyless Entry, wireless alarm and security systems, AMR-automatic Meter Reading, Consumer Electronics. Industrial monitoring and control).

c) Buzzer A buzzer is used here as an audio alarm and is a signaling device, usually electronic, typically used in automobiles, household appliances such as a microwave ovens, or game shows. Initially this device was based on an electromechanical system which was identical to an electric bell without the metal gong (which makes the ringing noise). Nowadays, it is more popular to use a ceramic-based piezoelectric sounder which makes a high-pitched tone. Usually these were hooked up to "driver" circuits which varied the pitch of the sound or pulse the sound on and off.
d) Touch Screen A resistive touch screen comprises several layers, the most important of which are two thin, transparent electricallyresistive layers separated by a thin space. These layers face each other with a thin gap between.

VIII. CONCLUSION The electronic menu card system helps the people to select the food items through matrix keypad. Radio frequency based communication technology is used here. The hotel people can read the items from each table at the PC display in kitchen to work it fast. This is very much helpful in star hotels and resorts where the preparation time is much greater. In our system we have only one transmitter and receiver. But in actual practice every table or room requires this digital menu card for their requirements. In future we can change this system to multiple transmitter and single receiver one by the help of MCU or computer, we can also add voice announcement along with the display. This system also ensures good quality of service and customer satisfaction. The proposed system has the potential to attract customers and also adds to the readiness of maintaining the restaurant ordering sections. Apart from this updating of menus can be done easily. Depending upon the family and ROM size of the microcontroller, the size of the menu list can be varied.
