Introduction:
The advances in the technologies related to wireless
communication has led to the emergence of several engineering
designs to aid the human requirements. As we all know
Agriculture play a significant role in developing country like India
and implementing mobile communication for facilitating farmers is
the basic idea of our project. Thus with the creeping interests in the
wireless and GSM based projects, we came up with this idea of
developing a simpler, multipurpose, cost-effective design to vote
via short message service (sms).
ABSTRACT
Using SMS Based Voting machine we can vote from our home
just by sending a
sms a specified format from our mobile. The entire voters will be
provided with a
unique password (pin) and identification number. For voting we
have to send a
sms in a predefined format. The voting machine will receive
this messages and
decode the message and verify the the Pin number and
identification number if
both number matches the voting machine will accept the vote
else the message is
rejected by the machine. The voting machine is implemented
using P89V51RD2
microcontroller .A GSM MODEM is used to receive messages
from voters. The
microcontroller accepts this message and verifies the message and
keep updates.
An LCD is used to display the result.
Our project is based on “GSM technology” used for long distant
communication. The design portion involves mainly a GSM
modem and a control circuitry with microcontroller and Max232N
etc…
For doing this project we use some of the software like
 Embedded C for programming the application software to
the microcontroller.
 Protel schematic software is used for designing the circuit
diagram for this project.
 Express PCB software is used for designing the PCB for
this project.
(Since PCB making is a big process and involves lot of
machineries, which are expensive, we are going to outsource this
to the manufacturer.)
Components used:
 Power Supply 5v DC 7805
 Microcontroller 89S52Atmel
 Crystal
11.0592MHz
 MAX232
Serial Communication
 Motor Starter
 GSM Transmitter and Receiver (MODEM)
1.INTRODUCTION
India is world’s largest democracy. Fundamental right to vote or
simply voting in
elections forms the basis of Indian democracy. In India all earlier
elections a voter
used to cast his vote by using ballot paper. This is a longtimeconsuming process and
very much prone to errors. This situation continued till election
scene was completely
changed by electronic voting machine. No more ballot paper,
ballot boxes, stamping
,etc .all this condensed into a simple box called ballot unit of the
electronic voting
machine. Cell phone based voting machine is capable of saving
considerable printing
stationery and transport of large volumes of electoral material. It is
easy to transport,
store, and maintain. It completely rules out the chance of invalid
votes. Its use results
reduction of polling time, resulting in fewer problems in electoral
preparations, law
and order, candidates' expenditure,etc. and easy and accurate
counting without any
mischief at the counting centre. The aim of our project is to design
& develop a
mobile based voting machine.
This Project focuses onto implement GSM (Global System for
Mobile
Communication) based Voting System. This system is
implemented using an
embedded microcontroller. The embedded microcontroller used
here is P89V51RD2.
Actually, the aim of the project is to implement an Automatic
Voting system. GSM
Based voting machine is fully controlled system. There is no
chance of any mistake.
Primarily, the system functions with the help of different
technologies like the
traditional cellular network such as Global System for Mobile
Communications
(GSM) and other radio frequency medium. Today GSM fitted
Banks, cars;
ambulances, fleets and police vehicles are common sights. The
functional units of our
projects are GSM MODEM, LCD display, P89V51RD2.

SIM card interface
You can use AT Command to get information in SIM card.
The SIM interface supports the functionality of the GSM Phase 1 specification and
also supports the functionality of the new GSM Phase 2+ specification for FAST 64
kbps SIM (intended for use with a SIM application Tool-kit).Both 1.8V and 3.0V
SIM Cards are supported. The SIM interface is powered from an internal regulator
in the module having nominal voltage 2.8V. All pins reset as outputs driving low.
Logic levels are as described in table below.
