The document presents a project on a Zigbee-enabled hotel menu ordering system that utilizes a touchscreen interface for customers to place orders. The system aims to improve ordering efficiency, reduce wait times, and enhance customer satisfaction by allowing orders to be transmitted wirelessly from tables to the kitchen via microcontrollers. Additional features such as payment integration through smart cards and feedback mechanisms are discussed as future enhancements.

2. Motivation of the project
 Irregularity in Ordering.
 Wastage of time.
 Customer dissatisfaction.
 Poor management.
 Increased manpower.

3. Objective Of The Project
 Aim of the project is to develop a prototype of a
system based on Embedded micro controller(PIC16)
which is used for ordering in hotel using touch screen
and graphical LCD.
 Also at the other end, a graphical interface is designed
for taking the orders from different tables and to give
the confirmation.

4. INTRODUCTION
 This project involves developing a prototype for customer self-
ordering system in restaurants or hotels.
 In the proposed system, Zigbee is used to transmit the data from
transmitter to the receiver. There is a Micro-controllers at transmitter
(customer table) and MAX232 at receiver (kitchen) provide interface
that is required to communicate microcontroller with RS 232 based
devices using serial communication link.

5.  Whenever a customer comes to a table, they can select their order with the
help of a Graphical LCD with touch screen provided. This GLCD displays
MENU items with its corresponding images or pictures, so the customer has
the choice of selecting the item with its picture. As soon as the customer
selects the item, it will be displayed on the PC provided in the receiver
section.

7. Power Supply Unit
 Power supply is designed to convert high voltage AC mains
electricity to a suitable low voltage DC supply for electronics
circuits and other devices.
 It can be broken down into a series of blocks, each of which
performs a particular function.

8. Zigbee
 Zigbee is a new global standard for wireless Connectivity.
 Zigbee is a Communications standard that provides a short range cost
effective networking capability. It has been developed with the emphasis on
low-cost battery powered applications.
 Zigbee defines mesh, star and cluster Tree network topologies with data
security features and interoperable application profiles.

11. HARDWARE REQUIRED
 Display (Graphical LCD)
 Touch screen (4 wire resistive)
 Buzzer (5/12 volt DC buzzer)
 ZIGBEE (Wireless Full duplex transceiver)
 Micro controller (PIC16f877a)
 Serial Driver (MAX232)
 Power Supply Unit

12. SOFTWARE REQUIRED
 A Cross compiler for compiling and linking the code written
for PIC16 (Mikro C/MPLAB).
 Serial communication software for downloading code to
PIC16(u CFlash PIC).
 Operating System: Windows 2000/XP/7.
 Application program development in Embedded C.
 GUI design using Lab-VIEW.
 Proteus SW for circuit simulation.

13. Application of project
 Hotels
 Restaurants
 Cinema halls

14.  The main drawback of the system is it does not give the feedback of the
requests to the user. This can be eliminated using GSM modem which
sends the SMS messages about the requests to the manager when the
responder does not respond to the requests of the user.
 The system can also extend using smart card technology through which
the bill payment can be done based on the smart ATM debit or credit-
cards directly. The printer can directly issue bills to the customers at
tables only.
