Advanced Automation System in Industrial Applications Using PIC Microcontrol...IJMER
The main aim of this paper is to design and develop an advanced automation system in the
industries. In this technique we are using the GSM modem which have the SIM card present in it, the
user can send message on the 10 digit SIM number using the cell phone from any part of the world. The
micro controller is programmed using the embedded C. when the user will send the message to a
particular device that particular device will be on or we can also off the device. Example if the motor is
in over voltage, under voltage, over current in that time the microcontroller will trip the circuit and give
the message feedback to the user. The micro controller will read the temp from the sensor and it will
display the same on the LCD when the incoming temp crosses the set limit the micro controller will turn
OFF the device and will send the message to owner using the SIM card present in the GSM modem. We
can also check the continuous status of the device.

Mobile robotic platform to gathering real time sensory data in wireless perso...Alexander Decker
This document describes a mobile robotic platform that uses wireless communication to gather real-time sensory data. The robots use Zigbee transceivers to transmit data like temperature and gas content to a control room over a wireless personal area network. A graphical user interface in MATLAB is used to monitor and control the robots. The system allows for low-cost wireless monitoring in applications like home security, mining, and hazardous environment monitoring where robots can gather data that may be dangerous for humans. Hardware and software components of the transmitting robot nodes and receiving coordinator node are discussed, including microcontrollers, sensors, wireless modules and the MATLAB GUI interface.
This document describes the design of a 6 degree of freedom robotic arm that can be controlled over the internet. Key points:
- The robotic arm uses servo motors controlled by a microcontroller to achieve 6 degrees of freedom like a human arm.
- A user interface created in VB.NET allows remote control of the arm over the internet by sending signals to the microcontroller.
- An Atmega32 microcontroller interprets the signals and generates pulse-width modulation signals to control the servo motor position and movement of each joint in the arm.

CHAPTER 1
1.1 INTRODUCTION
In democratic societies, voting is an important tool to collect and reflect people’s opinions.
Traditionally, voting is conducted in centralised or distributed places called voting booths.
Voters go to voting booths and cast their votes under the supervision of authorised parties.
The votes are then counted manually once the election has finished. With the rapid
development of computer technology and cryptographic methods, electronic voting systems
can be employed that replace the inefficient and most importantly error-prone human
component. To increase the efficiency and accuracy of voting procedures, computerised
voting systems were developed to help collecting and counting the votes. These include
Lever Voting Machines, Punched Cards for Voting, Optical Mark-Sense Scanners and Direct
Recording Electronic (DRE) voting systems.
For a variety of reasons, voters may be unable to attend voting booths
Physically, but need to vote remotely, for example, from home or while travelling abroad.
Hence, there is great demand for remote voting procedures that are easy, transparent, and,
most importantly, secure. Today, the most common way for remote voting is postal voting,
where voters cast their votes by post. However, it lacks proper authentication and involves a
time-consuming procedure. Internet voting was introduced to provide more flexibility.
Because of the inherited security vulnerabilities of the Internet and computerised systems in
general, Internet voting incurred a wide range of criticism. However, to date many pilot
projects in different countries and research groups have been carried out. We endeavour to
improve mobility and address security problems of remote voting procedures and systems.
We present an electronic voting scheme using GSM. With more than one billion users1, the
GSM authentication infrastructure is the most widely deployed authentication mechanism by
far.

2.4 MAX 232
Figure 5
The MAX232 IC is used to convert the TTL/CMOS logic levels to RS232 logic levels
during serial communication of microcontrollers with PC. The controller operates at TTL
logic level (0-5V) whereas the serial communication in PC works on RS232 standards (-
25 V to + 25V). This makes it difficult to establish a direct link between them to
7. GSM BASED VOTING MACHINE 2013

communicate with each other.The intermediate link is provided through MAX232. It is a
dual driver/receiver that includes a capacitive voltage generator to supply RS232 voltage
levels from a single 5V supply. Each receiver converts RS232 inputs to 5V TTL/CMOS
levels. These receivers (R1 & R2) can accept ±30V inputs. The drivers (T1 & T2), also
called transmitters, convert the TTL/CMOS input level into RS232 level. MAX232 needs
four external capacitors whose value ranges from 1µF to 22µF.

3.2 SOFTWARE SETUP:
3.2.1 ATMEL STUDIO 6:
Atmel® Studio 6 is the integrated development platform (IDP) for developing and debugging
Atmel ARM® Cortex™-M and Atmel AVR® microcontroller- (MCU-) based applications.
The Atmel Studio 6 IDP gives you a seamless and easy-to-use environment to write, build
and debug your applications written in C/C++ or assembly cod.
Atmel Studio 6 is free of charge and is integrated with the Atmel Software Framework
(ASF)—a large library of free source code with 1,600 ARM and AVR project examples. ASF
strengthens the IDP by providing, in the same environment, access to ready-to-use code that
minimizes much of the low-level design required for projects. Use the IDP for our wide
variety of AVR and ARM Cortex-M processor-based MCUs, including our broadened
portfolio of Atmel SAM3 ARM Cortex-M3 and M4 Flash devices.

CHAPTER 5:
5.1 ADVANTAGES
Democracy: All and only the authorised voters can vote, and each eligible voter can
vote no more than once. Voters can also choose not to vote.
Privacy: All votes remain secret while voting takes place and each individual vote
cannot be linked by any individual or authority to the voter who casts it.
Accuracy: The voting result accurately reflects voters’ choices. In this case, no vote
can be altered, duplicated or eliminated without being detected.
Fairness: No partial result is available before the final result comes out.
Verifiability: where any voter can check that her own vote has been considered in the
tally.
5.2 DISADVANTAGES
Cost of instrument is relatively high.
The SMS transition involves SMS server. This may introduce delay in delivering the
message. If it delivers after polling duration is completed then that vote is not
considered.

CHAPTER 6:
CONCLUSION & FUTURE SCOPE
We proposed a GSM mobile voting scheme, where the GSM authentication infrastructure is
used to provide voter authentication and improve voter mobility.
Authentication is always a difficult requirement to fulfil for remote voting schemes, most of
which apply a public-key based signature scheme for voter authentication. In our scheme, by
using the existing GSM authentication infrastructure, the public-key overhead is largely
reduced. Our scheme also enhances the security and provides more mobility and convenience
to voters.Where the voters’ privacy is protected by applying a blind signature scheme. In this
paper, we presented the basic structure and protocol of our GSM based mobile voting system.
However, further work is needed to address the importance we place in the trust on the
AC(Authentication Centre), and we are therefore investigating options for enhancing and
extending the GSM mobile voting scheme. In future work, we will discuss end-user device
(ME) and application security. We will also address how the voters obtain the voting
application and solutions to provide the integrity of the voting application running on the ME.
The Trusted Platform Module and smart card solutions will be considered.
