Sixth Week in Interactive Art

The sixth week of Interactive Arts 2 has reached a close. Most of my class activities were dedicated to watching the videos provided on the annoucements page since we were not meeting in class for this week. Here is a collection of all my activities and notes for this week.

On 2/11/25, I was not able to perform any activities for this class due to certain circumstances.

For 2/13/24, I was able to dedicate the entire day to finishing all of the announcement videos that were provided on canvas. Here are some of the notes I have written:

"sourcing/buying components and info about shift registers" video

  • What are Limit Switches?
    • A switch that has a clicker lever, that when pressed, sends a signal 
  • What is a Chassis Mount?
    • Sauderable metal pieces where wires and pieces are connected
  • What are Shift Registers?
    • Type of digital circuit using a cascade of flip-flops where the output of one flip-flop is connected to the next
      • Types:
        • Serial-in, parallel-out: Shifts data into internal storage elements and shift data out at any internal stages available for output
        • Parallel-in, Serial-out: Shifts data into any stages and then shifts out at internal storage
        • Surface mounts are harder to sauder due to their size
        • Used to connect switches
        • Has 15 pins
          • CLK: Clock
          • CLK INH: Clock inhibit; when high, no change in input
          • SH√LD: Shift/Load input, when high data shifted when low data is loaded from parallel inputs
          • QH: Serial output data pin, where steam of 1s and 0s come in
  • Tips:
    • Exclude market place products as shipping costs are worse
    • Data sheets show dimensions
    • Mounting holes for board makes it easier to mount on an object
    • USB are 5 volts
    • HV: High Volts, LV: Low Volts
"researching components" video
  • What is a RS232?
    • A serial port that connects to a computer or equipment that defines a connection between DCE (Data Circuit terminating Equipment; Ex: Modem) and DTE (Data Terminal Equipment; Ex: Computer)
      • Used -9 to 9 volts
      • Not for microcontrollers 
  • What is a TTL?
    • A serial port commonly found in UART (Universally Asynchronous Receiver/Transmitter) transmission method, a method found in most microcontrollers
  • What is a E2PROM?
    • A type of memory that saves parameter data
  • What is NEMA output format?
    • A type of format for serial communication found in GPS
  • What is 3v3
    • Regulated output from the onboard regulator
      • Can draw 700mA
  • Good brands:
    • Seeed Studios
    • ADA Fruit
"a quick TD example" video




This marks the end for Week 6. Looking forward to what's next for the upcoming week.

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 ...

Second Week in Interactive Art

Image
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 ...

First Week in Electronic Media

Image
My first week of Interactive Art II: Electronic Objects has ended. Here is a recap of all the things that happened during the week. On the first day, we covered the syllabus which had most of the things that would normally be outlined for every class including University Honor Policy, Attendance, etc. One of the only things that were new for this class would be how its course grading was divided which involved the following: 49 total possible points 1.4 for every Weekly Blog Posts (16 total) 4.7 for every Major Project Critiques (2 total) 9.7 for participation 2.7 for Presentation/Demonstration 4.8 for Contributions to Reading Discussions The other stand out thing also included some of the programs that we were going to be involved with: Arduino - coding program that we will be using to code devices for some of our artworks. Ossia Score - interactive sequencer for audio-visual artists  Discord - the application that will be used for online discussions Blogger - a website used to cr...
