 Reasoning
• Why I chose this idea.
 Introduction
 The
Problem
 Assumptions
 Solution
 Results
 Conclusion
In modern workplaces documentation has
become an large issue.
 In many cases some businesses will hire outside
companies.
 If an problem arises with improper
documentation a 5 minute fix can take weeks.
 With wireless technology becoming more
common place, maintaining a functional network
is crucial.
 The ability to have a handheld device that gives
clear identification of information appeared
promising.

I
have seen many cases where a piece of
wireless hardware was providing errors
and the location of the device was
unknown.
 This device is built off of an Arduino Uno
micro processor.
 This is a simplified version of the original
design.
 This device will detect access points
based off of their IP addresses.
 You
are the Network Administrator for a
company.
 The company operates within a compound
each building has wireless connectivity.
 You network management software has just
alerted you that an access point is reporting
errors.
 You have just recently started, and your
predecessor did not leave documentation of
access point locations.
 The software has provided you with the
access point's IP address
 Understanding
of network static IP
addresses.
 The network accepts static IP addresses
from devices.
 Problem access point is still broadcasting.
 Knows C programming language to some
extent.
 User has knowledge of electronic circuits.
 What
is the best way to find the access
point.
• Carry a laptop around the building continuously
refreshing a web page.
 Difficult to carry and use a laptop at the same time.
• Carry a laptop and use a wireless network
scanner software.
 Again, Difficult to carry and use at the same time.
• Network scanner app on a mobile device.
 Smaller screens and it will pick up multiple access
points to sift through all the IPs.
 What
is the best way to find the access
point.
• Purchase a hand held wireless signal scanner
 The company may not provide for a $1000+ piece of
equipment
• Build a portable, open source access point
identifier.
 Fully customizable, requires learning extra
components.
 The
device functions on a simple
process.
• Reads the broadcasted information from an
access point.
• Compares the information to the information
stored within its program.
• Reads out its results on a single LED.
• LED activating indicates that the IP address
matches the IP address within the program.
 Parts
required:
• Arduino Uno base unit.
• WiShield V2, Arduino wifi shield.
• Arduino programming software.
• One LED with wire for connecting to Arduino.
 The
set up of the hardware is fairly
simple.
 When connecting the LED, first select the
output pin desired.
 The
WiShield pugs directly on top of the
arduino base.
• The pins and shape of the extention board will match
up with the base.
Once
the desired pins are selected,
• Connect the ground pin of the LED to the
ground port on Arduino.
• Connect the positive lead of the LED to the
selected pin on arduino.
Once
the physical assembly is complete,
Arduino's programming software needs
installed on a computer system.
• The downloaded folder needs extracted.
• The software runs from the root folder, no
wizard setup.
• I also created a shortcut of the program .exe
file on my desktop for easy access.
 When
preparing to program arduino, the drivers
must be manually installed.
• Though computer management, look under device
management for the arduino device.
• The device will appear as a usb device that has
errors.
• right click on the device and select update driver.
• When prompted, browse the hard drive for the
extracted folder from before.
• Select the drivers folder.
• Allow Windows to search this folder and locate the
appropriate drivers for this device.
 Arduino
works on a programming
language that incorporates many
languages, Ones I have found include:
• C, C++
• HTML
• some PHP
 For
me, this took learning. I have only
scratched the surface of understanding the
language.
 Using example programs helped in
understanding the code.
 For
this demonstration, the program I
created connects to an open network.
• This is due to a known issue with the arduino
wireless shield.
• Some have been able to achieve in getting
arduino to connect to a secure network however
more often than not an open network is required.
• With arduino being open source, users are
encouraged to try to find solutions to problems
like these.
 The
arduino connected to the access
point successfully.
 The LED lit when the it detected the
appropriate IP address
 There is a slight delay when arduino
refreshes with the access point IPs.
Wireless Shield
Arduino Uno (base)
 The
 The
project worked well.
project does not exactly match my
original design but functions to the same
extent.
 During the course of this project I learned,
• Basics of C programming language
• Key lines of code used for Arduino’s outputs and
inputs.
• Communication with simplistic devices on a wireless
network
• The usefulness of and access points default
broadcasted information.
 Possible
cases to protect the circuitry that
can also allow it to be easier to handle.
 Addition of battery pack. The project
presently operates from the power from a
wall adapter. A battery pack would free up
use for the device.
 Modification to the code that will allow the
device to identify an access point based on
its MAC address.
Thank You!
