Motivation for the Project
 I am a driver and life would be much easier if I already
know where I’m going when I enter a parking area or a
building.
 I wanted to challenge myself on doing something I
have never done before.
 Learning about microcontrollers and the different
applications you can do with it is just so much fun.
Proposed Solution
 Using a microcontroller, program sensors which will
be displayed in a browser through the internet.
Why the internet?
 The internet makes everything easy for us nowadays.
We can know what happened in China here in the US
a few minutes after it actually happened there. It
basically made the whole world into a small town.
 Also, with the smart phones getting really popular
nowadays, a handy application like this can really help.
(especially on thanksgiving sale).
Why use Netduino plus?
 I was initially going to use the basic stamp that we
learned in class but as I did more research, I came
upon this really neat microcontroller that has a built in
ethernet port. It also gets its power from USB so I don’t
have to worry about building my own power supply.
 The Netduino plus is one of the latest microcontrollers
and a lot of people gave many positive feedbacks about
it.
Video
 This video shows the functionality of the project and
how it was built.
What do you not like about the
Netduino plus microcontroller?
 The memory is too small!
That’s all!
Here’s the block diagram
How does it work?
 A user gets his phone, laptop, ipad or anything that
can connect to the internet and has a web browser and
puts in the ip address or the url of the web server. In
my project’s case, since I haven’t registered for a
domain name yet, we can only put the ip address of my
web server.
 The user will then see a map of the parking area that
he wanted to go to. Each parking spot is color coded by
either red or green. If it’s green, the spot is available
and red if it’s not.
Parts and Equipment used
Microcontroller parts were ordered from Adafruit
Industries
 Netduino plus, USB cable, 10k ohm resistors,
breadboard, light sensors
 Router (thanks Dr. Rawat)
 Soldering Machine,wires, pliers (thanks Dr. Vigs)
 Ethernet cable (thanks to my roommate Zhou Yi)
 Iphone 4 for recording( thanks to my other roommate
Bunleng Chan)

Conclusion
 It worked well and “almost” according to my initial
plan.
 I wanted to add more functions on it but didn’t have
enough time.
 I had a lot of fun learning about microcontrollers.
Future Work
 Adding more functions into it like texting or
automated voice operator.
 Having an actual phone app for it.
 This idea can be used on many different applications
like checking if certain items are still available or not.
