Recitation2 Arduino basis (Katie)

the first two circuits are easy to build. Just connect as the schematic suggests.

For the second circuits, we change the code in order to change the melody, it’s pretty fun!

The third one is quite difficult. We need to first read the schematic, not only to know how are the wires connected but also how the electricity flows between each component. The first time we upload the code, it doesn’t work. Later we found out that we forgot to ground one of the LEDs. The 10k ohm resistor is in parallel connection with the switch. and the 220 ohm resistor is in series connection with the LED. There’s another problem I encountered in the drawing of the schematic: no mater how I draw it, two of the wires always run across each other. With the help of Jingtian, I know how to draw the crossing but not connected wires.

Q1: I feel like I’m involved with technology anytime and anywhere. Even when I’m taking the piano courses, we use the electric piano to practice: every one plug in their headphones so that what they are playing can only be heard by themselves. It’s really convenient since there’s 8 people in our class, with the help of this technology, we can practice together and not disturbing others. This improve the efficiency of the class a lot. Also, I am sometimes consciously reducing my time of using phones. We are so used to phones. My definition of interaction: two or more agents response to each other through a medium. The two agents don’t have to be humans, they can also be machines. 

Q2: To protect the button from to much current.

Q3: I’ll make an LED carpet to put in my dorm that can change the brightness of light according to the environment.

Week3 response to I am sitting in a room (Parren)– Katie

In the first nine minutes, I can clearly tell apart every word in the sound. After nine minutes, it becomes hard but I am still trying to distinguish words. At around perhaps 20 minutes, it becomes impossible to distinguish.  And every three or four minutes, the tone will change. It starts with a few sentences and ends up with some not so beautiful melody. It actually reminds me of monks chanting. Every time I go visit a temple, there’s a group of monks chanting and the sound is loud. I cannot tell what wards they speak.

For this art piece, I feel it’s quite philosophical. In a little room, the concept of sound and language has been overturned and redefined. In the endless reputations of recording and getting feedback from the room, “language” has been erase during the process and “room” has became more and more abstract. It can extend to any of the spaces.  The coexistence of the artist and the sound within the same room. I feel like the artist is telling us that we are supposed to hear the room, not the person. And the whole art piece contains not only the room, the artist and the sound, but also all the listeners.

Assignment 2 – Generative Vizzie Visuals (Parren)—Katie

https://gist.github.com/JiayanLiu27/3039ede61b83d17cad877bb53fdba290

Here’s a link to my code.

First I put a starter to begin my patch.  then I add third players and inserting videos . After that, I am just randomly trying different objects to remix them. I play around with transform modules and effect modules: I use a rotator, a zoomer, a freezer, a delayer and a husalier.

Week2: Reading response Synesthesia (Parren)—Katie

            When we listen to music, I believe everyone has their own visuals. For example, every time I hear Pharrell Williams’ song Happy, the visual in my mind is a yellow smiling face. I think most people will link higher notes to brighter colors and lower notes to deeper colors. I am a big fan of a Chinese pop singer and I have been to many of his live concerts. The lighting designs and his clothing are very different in different songs. It is pretty true that different shapes, directions and colors of lighting enhances audience’s experience of hearing the music both in ears and in eyes.  In particular songs, he wears the same color of costumes every time he sings it. I believe in his mind, every song has its own color. Imagine that if there is only a bright yellow spotlight throughout the whole concert, the listening experience would not be so rich. Then the question brought up to me is: why do more people like to enjoy live concert rather than listening to albums?  One of the explanations I come up with is that visual component is very important in audio experience.

             I have the feeling that having synesthesia for artists is actually a good thing because many art forms requires multi-senses. In the reading, Emrich, Neufeld and Sinke concluded: “synesthesia is not an illusion in the minds of those concerned but a genuine neurophysiological phenomenon that can provide science with unique insights into human perception” (420). It’s quite surprising for me to know that synesthesia is not a mental effect but a physical one.

Week 1: building circuits & soldering (Lee)–Katie

In the recitation, we are asked to build 3 simple circuits.  In high school I had some experience building the circuits but I never used a  bread broad. I used to see every wire I connected. The problem with bread broad is that I cannot see every wire, so the first step is to get familiar with how the bread broad is connected within.  The second step is to know what the materials look like. me After acknowledging these, it becomes easy for me and my partner to build the circuit.

These are materials needed:

  • 1 * Breadboard
  • 1 * LM7805 Voltage Regulator
  • 1 * Buzzer
  • 1 * Push-Button Switch
  • 1 * Arcade Button
  • 1 * 220 ohm Resistor
  • 1 * 10K ohm Resistor
  • 1 * 10K ohm Variable Resistor (Potentiometer)
  • 1 * LED
  • 1 * 100 nF (0.1uF) Capacitor
  • 1 * 12 volt power supply
  • 1 * Barrel Jack
  • 1 * Multimeter
  • Several Jumper Cables (Hook-up Wires)

The first circuit we built:

As we are building, the first problem occurs is that we do not know how to make things grounded. We even want to connect the wire onto the floor. With the help of Inmi, we know that the ground is the cathode of the bread broad. And it’s worth noted that always use a darker color to ground.

This is the second circuit:

Another problem is how to put the switch. We think how we connect all the materials are right but the light is always on, it doesn’t control by the switches. Later after we looked at the diagram we found out that the four legs are not equal. A and D is connected and B and C is connected. You can only place the switch in a certain way. We then change the way we put the switch and it works. 

This is the third circuit we built:

  

Answer to the question: 1. Interaction is a process of act and react. That is to say, one throw a message to the other and the other one process the massage and throw it back.  When building circuits, we give the circuits messages and get feedback from it. If the light is not on or there’s no sound in the speaker, we will improve on our currently built. So it’s a way a interact.

2. Speaking to interaction and art, what most impressed me is teamlab’s work. I went to an exhibition of teamlab in  shanghai this summer. It was really beautiful and interactive.  The images on the wall will change according to your different pose and position.
