Under pressure

Named after that song from Queen, now I have to program the arduino to recognize an analog input. Meaning, it’s not just as simply flipping a switch. This requires and entirely different mindset.

pcomp

Using a knobthingy commonly known as a “potentiometer”, it allows the light to switch on once you turn it past a certain point. Notice that the potentiometer does not use a resistor and is an exception to the rule.

Now I wanted to control the intensity of the LED using a light sensor. So I ended up with this. It still needs a bit of tweaking on the range the sensor recognizes but it more or less captures the desired result.

I’m still working on two LEDs and two pressure sensors.

Animated Ramen

This particular homework was problematic at the coding level at first. Working with Alex, my assigned partner we figured out on how we’d like to animate our projects and went to work.

I went through 3 different revisions of the code posted last week since now I had to add “void setup” and “void draw”. One will setup the set elements into the sequence and the other will animate.

The bowl was problematic at first as it kept saying I was mixing “active” and “static” elements. I then moved the bowl code to be included in the “void setup” command and it worked! Now the problem was how to animate.

At first I could get the “mousePressed” command to work properly. I gave up on that code at first and moved on to another code to use. I ended up without control in the case of my ramen. Everywhere I moved my mouse it just spread the “ramen” code all over the screen.

So in frustration I gave it a rest. Then in one lazy Sunday morning I figured it out! It turns out that I lacked a closed curly bracket

And here’s the final product. Click on the mouse to add the ramen and for the final touch, press the spacebar for the eggs, spring onions and chopsticks. Enjoy!

Ramen!

What are the sensors in my neighborhood?

This weekend while taking the subway I noticed a number of physical sensors that I didn’t notice before.

sensors

This particular button is not common in New York well at least I haven’t seen much of it in Manhattan. But pressing this button will tell the traffic signal light that there is a pedestrian who wants to cross and the light will change shortly afterward. But then again, it could be a placebo effect, giving the user the illusion that the light will change soon but in reality, it’ll change when the program tells it to change.

sensors

Here’s a light that doesn’t have a sensor but in my opinion needs one. I see three different sensors that could work here. One is light sensor, which would tell the streetlight to turn off once it detects a particular amount of light (supposedly sunlight) to detrmine it’s on and off. Another is solar panels so it’s not too bad that the light is on all the time since the light is powered by solar energy. Then the third sensor would be the exisiting sensor which is based on time. Much like water sprinkers, these are set on a timer where the on and off is determined by a timer on the switch.

sensors

The Metrocard machine is a plethora of sensors. There are the input buttons on the touchscreen. There’s the numeric keypad for credit card and debit card holders to enter their information. The coin and bill sensors that determine US legal tender is being inserted into the machine. The braile pads that help the blind in getting their passes. And then of course the Metrocard slot where the machine either accepts or dispenses the card and reads how much is left on the card.

sensors

Of course what’s a Metrocard without the sensor that you use it on. Other cities such as Singapore, Tokyo, Hong Kong and London use RFID cards instead of the magnetic strip that the NYC transit system uses. I first used the Metrocard in 2002. I was used to the tokens all this time that it took a while to figure out which direction the magnetic swipe had to be for it to work.

sensors

I’m not sure if it can be seen here but I suspect the subway is outiftted with all sorts of sensors. Most of it detecting the position of the trains. This particular sensor at the station, I guess that sensor tells all the other trains along the line that there is a train present at this station and informs the other stations down the line with the announcement ” There is a Manhattan bound train one station station away.”

I saw this at church today. This emergency light has an electrical sensor. In the event of a power outage, these lights turn on.

Sensors

These exterior lights can be switched to detect motion in the event someone walks in front of the range of the sensor. This is great at night so you don’t have the light on all the time.

At the MOMA there is this device. Though not part of the installation but still has the “do not touch” warning next to it, I could guess that thsese are motion sensors that detects the presence of someone in front of the display. This is only present on displays that use a monitor and will then play the video once there’s a person in front of the display.

The displays are each identified with QR codes which directly links the viewer to a website with more information about the artwork. Of course in order to read this, your smartphone should have a QR reader.

Barcodes on everything is no different. These help stores and companies track inventory as well as make purchases accurate and efficient at the checkout counter.

If I see anything more before Wednesday, I’ll update this post.

Talk to Me @ MOMA

The “Talk to Me” exhibit at the Museum of Modern Art in New York is appropriate for the timing of the show and the scope that it shows. The show in my opinion basically conveys, everything is interactive.

ttmmoma

Even though everything is interactive, there are varying degrees of interactivity. Some installations required you to actually touch the display in order to see the “magic” that occurs, others were visual displays of the results of the device created.

ttmmoma

But as static some displays were, the exhibition itself had a degree of interaction from the mere scanning of a QR code in order to get more information about the work.

ttmmoma

But now what if these codes were ported elserwhere.

ttmmoma

I would describe interactivity as both parties to the action are aware that there is a response being waited upon each action compared to the idea where a static work such as a book.

Even though we interact with the book by reading it and reacting to the words on the page, it’s not interactive. It’s participation. The book does not expect a response from the reader nor does it care (Crawford 2003).

The museum experience is usually participatory as we willingly enter and absorb the works that stand before us. Like Monet’s “Water Lilies”, the benches that sit before it on the 5th floor of the MOMA invite the visitor to sit in front of the installation and look at the painting.

This is in stark contrast to the “Talk to Me’ exhibit.

I believe interactivity is where the work is complete once the intended user completes the cycle to which the art is represented. I see it very evident in the augmented reality works. They may range from the QR code in the field (pictured above) or the fact that USB ports stuck on the wall invite users to stick their computers next to it to download an image into your computer.

The Hungy Hungry Eat Head needed users to hold augmented reality cards for the program to put animated heads over their bodies displayed on a giant screen for everyone to see.

Augmented (hyper) Reality : Augmented City 3D

Though these works in augmented reality were not interactive at the show, at the time of their creation to the public is highly interactive. Though I believe the Augumented City 3D is conceptual in its “Minority Report” likeness but everywhere. It shows on how the tech can take us in that direction.

But not everything on display was as interactive as others as there are varying levels of interactivity with the work.

The Bat Billboard I believe is one example where it is not human interactive but instead bat interactive. We humans just watch the response on the billboard to describe the actions of the bats.

I found the BBC Dimensions exhibit particularly interesting where it uses existing data such as the length of the moon walk by the crew of Apollo 11 in real scale or like how long the mars rover travelled. It gives us who are not involved in theses events but curious to know about the information a sense of the scale of these events were traced out to our neighborhood which brings it closer to us.

Of all the works I do enjoy the fact that LIttle Big Planet made it to the exhibit in comparison to all of the “interactive” videogames out there. I believe this is the closest to mass market interactivity we can get that is not essential as compared to ATM interfaces, metro and oyster card dispensers. The level of user intervention in the game takes it beyond the participatory nature of media and instead turns it into something else.

Maybe in the next exhibit we’ll have to redefine “interactivity” once again. But for now, the future looks promising.

Christmas lights

There’s satisfaction to be had in watching lights blink especially when those lights turn on by your command.

greenredlight

The code is relatively simple enough now that I’ve had the weekend to digest the meaning of all these pins and ports.

//double lights green light and red light
void setup(){
pinMode(3,INPUT); //SWITCH
pinMode(5,OUTPUT);
pinMode(4,OUTPUT);
}
void loop(){
// if (digitalRead(3) == true) {
digitalWrite(5,true);
digitalWrite(4,false);
delay(500);
//}
// else {
digitalWrite(5, false);
digitalWrite(4, true);
delay (500);
// }
}

Using the same setup but different program and allowing the “if”s and “else” commands, this tells the chip to perfrom an action that will respond differently. In this case, when the switch is pressed the light will either be switched between red and green.

Feeling a little bold, I added more lights.

Trying something out

I wanted to get the switch to cascade the lights using the code below but it seemed that it wasn’t reacting to the switch and thus acting on switching the lights on it’s own. I’ll work on it some more.

//christmas lights
void setup(){
pinMode(9,INPUT); //SWITCH
pinMode(2,OUTPUT);
pinMode(3,OUTPUT);
pinMode(4,OUTPUT);
pinMode(5,OUTPUT);
pinMode(6,OUTPUT);
pinMode(7,OUTPUT);
// pinMode(8,OUTPUT);
}
void loop(){
if (digitalRead(9) == true && digitalRead(2) ==true){
digitalWrite (2, true);
delay(1000);
digitalWrite (3, true);
delay(1000);
digitalWrite (4, true);
delay(1000);
digitalWrite (5, true);
delay(1000);
digitalWrite (6, true);
delay(1000);
digitalWrite (7, true);
delay(1000);
// digitalWrite (8, true);
//  delay(1000);
//digitalWrite (8, false);
//delay(1000);
digitalWrite (7, false);
delay(1000);
digitalWrite (6, false);
delay(1000);
digitalWrite (5, false);
delay(1000);
digitalWrite (4, false);
delay(1000);
digitalWrite (3, false);
delay(1000);
digitalWrite (2, false);
}
}
