Second Week in Interactive Art

The second week has officially closed.

Here is a collection of all that happened this week in class:

On 1/14/25, we went through all 25 sketches for every student. And out of all my sketches, I was able to filter down to these two sketch ideas:



For number 24, the idea was loosely based off of brain surgery. It involves the viewer grabbing a needle and poking different parts of the mannequin's brain. And depending on where they poke in the brain, the eyes on the mannequin will show a projection of a video of some sort.

For number 25, the piece involves placing a "paper-looking" dunce hat on a pedestal and everytime the audience wears it, it will play audio files of a voice saying terrible stuff about them.

Once the discussion concerning our sketches ended, Robert assigned our first lab to do. It involved utilizing a bread board, leds, resistors, and connectors to make the led light up. I was able to finish the lab on the same day, here is a video of that experience:



There were also lecture videos that accompanied the lab. The videos discussed the following:
  • What is AC (Alternating Current)?

    • The power that comes out from a wall socket
      • Measure amount of electricity in volts
        • Usually 110-120 Volts in America


  • What is DC (Direct Current)?
    • Power that comes from the batteries


  • What is Ohm's Law?


What is the Power Triangle?


What is a Multimeter?
  • Measaures volts, currents, and resistance

Additional notes
  • Volts (V): Push electricity out
  • Resistence (A): Pull electricity in

On 1/16/25, we went over the second lab. It involved experimenting with the bread board, resistors, a potentiometer, and a multimeter. It was meant to help us get used to measuring volts, amps, and current but we were unfortunately I was not able to get through all of the exercises. Despite this, I was able to get some notes:

Schematic of Multimeter and Resistors Experiment:


Multimeter Notes: 
  • Black Cord goes to "COM"
  • VΩmA = Measuring volts, amps, and milliamps
    • Where red cord typically goes 
  • 10 ADC = 10 amps measurement
    • Dangerous
  • When you are measuring volts, amps, etc. set multimeter as close to the measurement as possible without going under

What is a Potentiometer?
  • A knob device that can change the number of volts coming out of the source

What is a Short Circuit?
  • A circuit with no "work" where electrons flow freely to battery
    • Very dangerous and can lead to fires
What is an Open Circuit?
  • A part of the circuit is open where electrons stops flowing through the system
    • How Switches work by closing and opening the circuit

That was all we covered for this week, with very interesting concepts. I am looking forward to next week.

Fifth Week in Electronics Media

Image
The Fifth Week in Electronics Media has ended. This is what happened for this week of class: On 2/4/25, we experimented with the new software, TouchDesigner. It began with the preparation of a breadboard circuit, as well as a serial write and a serial print code in the Arduino. Once the circuit and coding was set up, we connected the breadboard to the lab computers and opened TouchDesigner. Unfortunately though, I was not able to get as far compared to everybody else as I was stuck on the text TOP function and it was not working regardless of how much I fixed it. Though I did record a bit of notes which involved: What is the difference between a Serial.write and a Serial.print Serial.write sends bytes to the serial port Serial.print sends ASCII characters  For 2/6/25, I wasn't able to participate in class as I was not feeling well that day and had to unfortunately stay home. To make up for my absence, on 2/8/25, I went through the 2 hour TouchDesigner tutorial provided on Canvas an...

Fourth Week in Interactive Art

Image
We have now finished our 4th Week of Interactive Art. Here is a list of what happened. On 1/27/25, I was able to spend some time and completed Lab 5. Here is some of the notes and footage I recorded while I was performing Lab 5: Notes: What is an Ultrasonic Proximity Sensor (SR04 in kit)? Provides a way of detecting objects at a distance between 2-400 cm Arduino sends a pulse to the sensor's trigger, causing the sensor to send out a burst of ultrasonic sound When the sensor receives the echo, it raises its echo output to a HIGH level Distance it senses is encoded in the length of time that the Echo pin is HIGH What is the DHT11 Temperature and Humidity Sensor? Can provide temperature and humidity information to the Arduino with just one wire What are the LCD Hardware Pins? VSS: Ground (GND) VDD: 5V power for display V0: Contrast adjustment, connected to potentiometer wipers RS: Register select RW: Read/Write pin to select how the Arduino should communicate E: Enable pin (LCD works ...
