Sixteenth Week of Electronics Media

Today marks the end of the Sixteenth Week of Electronics Media. The end of the semester is right around the corner with only 2 days left until our project 2 critique. Here is what I have accomplished for this week.

On 4/13/25, while I forgot to create a blog for that week, I did accomplish in gathering all the materials I needed:

  • All the 3D parts that was listed on Week 14th for the Linear Motion Crank Shaft
  • 37mm 600rpm geared DC motor 6mm shaft (https://www.amazon.com/dp/B0C7GN1VPD?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1)
  • Sparkfun Sound Detector (https://www.amazon.com/dp/B01B26UBYA?ref=ppx_yo2ov_dt_b_fed_asin_title)
  • Gravity Voice Recognition Module (https://www.amazon.com/dp/B0C5XG3BXW?ref=ppx_yo2ov_dt_b_fed_asin_title)

I used the day to also assemble the crank shaft and here is the assembled module:



This is where space that will hold the motor and lever module.



This is the shaft attached to the motor.

On 4/22/25, I took the time to assemble these parts together and created a demonstration code that would activate the motor. Here is a demonstration of what that would look like:


   This is the motor by itself.


This is the motor moving when attached to the module. As you can see currently there are still some kinks to fix in terms of its continuous motion, but for now this helped confirmed that the programming and the motor at least works, the only problem lies in the module itself which I plan to fix. I also received a limit switch from Rob that would help me control when I want the motion to stop.


On 4/24/25, I researched the datasheet of the limit switch I received and how I can use it. 


I also took the time to look up coding tutorials and see how I can implement it to the motor coding. Here is the source I referenced: https://arduinogetstarted.com/tutorials/arduino-limit-switch

Here is also what the code would look like:


Currently the code works but it suffers from the same stop motion as the program without the limit switch and the switch does not work consistently

I also create another program using the voice module I have, although currently it does not work:




This marks the end of the Sixteenth Week of Electronics Media. I plan to use Sunday and Monday to tweak the code and assemble the entire project. Looking forward to presentation day!

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 ...

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 ...
