About this projectProject Description
aNonY is a place where Generation Y expresses themselves in transitions between the physical and digital world. They come in and out of Moffit having to enter this non-space transitioning to and from the professional life track of school/future ambitions and personal lives dispersed throughout the city.
The experience in this non-space captures this moment of transition by enabling individuals to express themselves physically on the walls and digitally to the world. Never before has this moment of transition been captured.
The space demonstrates mass transition by enabling individuals to activate the wall with their ID card and type a word that is on their mind based on a prompted part of speech to modify part of an existing sentence. This sentence is projected onto the wall while light is projected back at the individual from the windows on the same wall. Mass transition is captured as each sentence on the wall represents the contribution of seven different individuals.
We envision capturing all words and sentences digitally on a web feed so the broader community can view the expression and become enticed to physically experience the transition, collaboration, and contribution themselves.

Does this place have any special meaning to you?
Yes, because I walk through it every day, this is one of my campus homes. I walk between the BCNM Commons to here, the entrance to the ladies bathroom, all the time, every day.
Is there anything that stands out to you in this area?
It’s brutalist architecture, which I like. I think more of it on this campus is good than bad, but I’m in the minority of people who think that. I like that it’s shaded, I like concrete a lot. I like this space a lot!

Does this place have any special meaning to you?
I actually hardly ever notice it, it doesn’t really mean anything to me. I use it to get down to classrooms or use the bathroom in Moffitt.
Is there anything that stands out to you in this area?
It’s actually a big space and the sound is really nice in here. It seems noticeably unused or underutilized. There’s no sunlight, it’s all concrete, and I don’t think you get very much cell phone reception in here.

Does this place have any special meaning to you?
This is the first time I’ve ever walked through here. It’s dark, and kind of weird.
Is there anything that stands out to you in this area?
It’s especially weird because there’s this nice looking entrance over there, but then right here it’s sort of underground garage like.

transitioning away from the old idea..<
>We noticed there were many objects and an opportunity to create a gallery feel, but the barrier to participation to leave an object was too high. We also felts like we weren't maximizing the potential of the space.
coming to a new idea..<
>We still wanted to enable individuals to be able to express themselves in a collaborative, yet private way. We also wanted to capture more sensory elements of the space in an expansive way. Furthermore, we believed we could increase the participation and use of this non-space.
we decided to go with projection..<
>This enabled us to play with lighting in the space, project individual expression in a literal way, and enable individuals to leave their mark.
we decided to build software and go with words..<
>This enabled us to make the entry barrier next to nothing. It also allowed us to come up with a creative, collaborative way to intersect digital, physical, and dynamic participation that is constantly developing and changing over time.
we decided to go with RFID..<
>This enabled us to facilitate mass participation by make the system only work with multiple users.
we decided to go with foam core..<
>This allowed us to hide laptops and the projector and create a unobtrusive but noticeable / inviting experience. Presentation Slides
Step by StepStep 1: Cut out foamcore boxes and arrow
Create the two boxes out of foamcore to our specifications. One box to hold the projector and one laptop, the other to house the second laptop, RFID scanner, keyboard, speakers, arduino and plaque. Cut out an arrow to highlight where the interaction takes place.
Step 2: Cut Footprints
Using our footprint file, cut out vinyl footprints to lead people into the installation
Step 3: Download necessary code
Install Node and all of its dependencies, then run the code hosted on our github. Make sure the arduino is loaded with the arduino code, and to change the serialport to your specific port. After that, you can run the node server.
Step 4: Set up Laptops
The laptop (1) connected to the projector should just be mirroring the screen on the laptop (2) connected to the RFID scanner and keyboard.
2 should be running the node server, and have the arduino, keyboard, RFID scanner, and speakers plugged into it. the scanner should be taped to the top of the box so that people can scan their IDs.
Step 5: Enjoy!
Watch your sentence evolve!

The Arduino Uno has undergone many revisions, and hence the power supply circuit has evolved to an almost foolproof design. In this project, we will learn about the four different ways in which we can power up the Arduino Uno. While making projects, it is necessary to know the following techniques, since there are instances when flexibility with regards to the power supply is required.

Things required to power up the Arduino Uno
We are going to need the following apparatus to learn how to switch on the Arduino Uno.

What is the procedure to power up the Arduino Uno?
Modern Arduino Uno boards allow the board to have more than one source of power to be connected simultaneously. An intelligent switching circuitry ensures that the highest available voltage is selected and sent to the onboard voltage regulator and eventually powers up the board.
We can power up the Arduino using power supplied from the computer via a USB cable and/or by using external power sources.
1. Using USB cable
The USB port of the Arduino Uno can be connected to a desktop/laptop. If the connection is enumerated, i.e. the computer recognizes the device, the current supplied to the board is 500mA at 5V. If the connection is not enumerated, 100mA is supplied at 5V.
It is the process by which the host computer identifies a device to load the appropriate driver and learns the capabilities of the device
2. Using an AC to DC adapter plugged into the barrel connector
The barrel connector can be supplied an input of 7-12V. This is regulated to 5V by the onboard voltage regulator, and the board is powered on.
3. Using 5V input
It is possible to power up the Arduino using the 5V and GND pins, provided that the input given is steady and regulated 5V. The 5V pin bypasses the voltage regulator and all the safety measures present on the Arduino Uno, so if the input exceeds 5V (5.5 is the maximum upper limit), the board can be damaged. It is generally advised to avoid powering up the Arduino Uno using this method.
4. Using batteries greater than 5V
Connect a 9V battery with the positive terminal connected to the Vin pin and the negative terminal connected to the GND pin. The Vin port allows an input between 7 and 12 Volts, but we recommend to use a 9V battery. Depending on your application you can input 12V too but make sure the current values stay around 500mA.
Precautions to be undertaken before switching on the Arduino Uno
Troubleshoot
If the Arduino Uno fails to be recognized by the host computer, it’s possible that it won’t draw enough current. To fix this, try to use a USB 2.0 port if you were using a USB 3.0 port. In addition to that, you can also try changing the USB cable. However, if none of these work, you can manually install the Arduino Uno.
