During this recitation I did not encounter any issues with setting up the potentiometer that would control the intensity of the tint applied to the video. This took me about 30 minutes. After that, I was struggling with the button that would not work correctly. When I sought help, it turned out that nothing was wrong with my code, it was just some unknown malfunction. This issue remained unresolved…

The video of button malfunction:

The video of working potentiometer:

The Processing Code:

import processing.serial.*;
import osteele.processing.SerialRecord.*;
import processing.video.*;
Movie myMovie;


Serial serialPort;
SerialRecord serialRecord;

boolean buttonWasPressed = false;

void setup() {
  size(512, 288);
  myMovie = new Movie(this, "Jing'An.mp4"); 
  myMovie.loop();

  size(500, 500);

  String serialPortName = SerialUtils.findArduinoPort();
  serialPort = new Serial(this, serialPortName, 9600);

  // If the Arduino sketch sends a different number of values, modify the number
  // `2` on the next line to match the number of values that it sends.
  serialRecord = new SerialRecord(this, serialPort, 2);
  background(0);

}

void draw() {
  if (myMovie.available()) {
        myMovie.read();
  }

  serialRecord.read();
  int potentiometerValue = serialRecord.values[0];
  int buttonState = serialRecord.values[1];
  
  println(buttonState);
  
  if (potentiometerValue == 1023){
    filter(INVERT);
    image(myMovie, 0, 0);
  }
  else{
  float filterValue = map(potentiometerValue, 0, 1023, 0, 255);
  tint(filterValue, 0,0);
  image(myMovie, 0, 0);
  //if (buttonState == 1){
  //  tint(filterValue, 0, 0);
  //  image(myMovie, 0, 0);
  //  buttonWasPressed = true;
  //} else if (buttonState == 0 && buttonWasPressed == false){
  //  fill(255);
  //  rect(0, 0, width, height);
  //}
  }
}

The Arduino Code (just SendMultipleValues code with corrections):

#include "SerialRecord.h"

// Change this number to send a different number of values
SerialRecord writer(2);
int BUTTON_PIN = 9;

void setup() {
  Serial.begin(9600);
  pinMode(BUTTON_PIN, INPUT);
}

void loop() {
  int potentiometerValue = analogRead(A0);
  writer[0] = potentiometerValue;
  writer[1] = digitalRead(BUTTON_PIN);
  // if (digitalRead(BUTTON_PIN) == HIGH){
  //   writer[1] = 2;
  // }
  // else {
  //   writer[1] = 1;
  // }
  writer.send();

  // This delay slows down the loop, so that it runs less frequently. This can
  // make it easier to debug the sketch, because new values are printed at a
  // slower rate.
}

The rest of the recitation (like 15 min) I ended up just working on my final project. 

step 1.1: stand design

I was the partner “A” and it took me about 15-20 minutes to get all the parameters right. I did not encounter any particular issues as the instruction was fairly clear. The most confusing thing were the little circles that were meant to later hold the servo inside (like the distance from the rectangle). At first, I didn’t realize that the GIF in the instructions showed how to do it, so it took me a little longer.

My parter got her part done even faster:) so we decided to merge the design and.. well, it went good. 

I was very confused why the gaps on the left down side of the parts were not on the same y-axis and checked the measurements like a 100 times. I sought for help and one of the fellows reassured me that it is alright. It indeed turned out to be alright (as I later saw how this benefited the stand). But yeah, this part went fairly quick. 

step 1.2

as we started to create our pattern design, in about 5 minutes, the first group of people were invited to go to FabLab. So, we decided to finish up really quick and go. I didn’t get a chance to look at my partner’s design because of that. unfortunately, she somewhat misunderstood the way the laser cutting works and created the design that would basically fall apart in a lot of pieces straightaway. 

It looked like this:

so when we went to FabLab we were unable to laser cut it from this, hence we came back and we quickly changed the design by deleting some outlines and thickening the others.

My design looked like this:

step 2: Laser cut

when we returned, everything worked great! absolutely no issues occurred here!

step 3: assemble

here as well, we assembled the thing pretty quickly, making it in time by the end of the recitation! we did not need the screws to make it work. you can see it running on the sweep example down below:

it was definitely a great experience and the fact that we were able to create something this cool so fast is fascinating!
