VOICE OPERATED MODERN RESTAURANT
AIM:
The main aim of the project is to design a system which can get orders from distant
area through voice alert.
PURPOSE:
The purpose of the project is to implement a system based on a voice in restaurants to
take the menu order and to transmit this information to the receiver section.

DESCRIPTION:
RF transmitters are electronic devices that create continuously varying electric
current, encode sine waves, and broadcast radio waves. RF transmitters use oscillators to
create sine waves, the simplest and smoothest form of continuously varying waves, which
contain information such as audio and video. Modulators encode these sine waves and
antennas broadcast them as radio signals. There are several ways to encode or modulate this
information, including amplitude modulation (AM) and frequency modulation (FM). Radio
techniques limit localized interference and noise.
In this project the microcontroller which forms the heart of the project, plays an important
role in establishing communication between transmitter and receiver. The microcontroller
communicates with RF technology and sends the data from RF transmitter to receiver section.

This project consists of two sections one is transmitter section and other is receiver
section. Both sections communicated using RF technology. The order information is
transmitted to the receiver section via RF wireless communication. According to that order
which is transmitted to the receiver we will get a voice announcement through speaker. Here
LCD is used to display the data on LCD. So that the order information is given at the
restaurants using RF communication
This project uses regulated 5V, 500MA power supply, 7805 three terminal voltage
regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the
ac output of secondary of 230/12V step down transformer.
