Recitation 9—Vivien Hao

For this recitation exercise, I have decided to include one of my favorite song cuts. While I move the potentiometer, the image of the video would change a little bit. 

This is my Processing code:

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

String myString = null;
Serial myPort;


int NUM_OF_VALUES = 1;   
int[] sensorValues;      


void setup() {
  size(500, 500);
  myMovie = new Movie(this, "JJ Lin.mp4");
  myMovie.play();
  setupSerial();
}


void draw() {
  updateSerial();
  printArray(sensorValues);
  float hcy = map (sensorValues[0],255, 1023, 0,100);
  if (myMovie.available()) {
    myMovie.read();
  }
  tint(hcy, random(100), random(800)); 
  image(myMovie, 0, 0);
}



void setupSerial() {
  printArray(Serial.list());
  myPort = new Serial(this, Serial.list()[ 1 ], 9600);
  // WARNING!
  // You will definitely get an error here.
  // Change the PORT_INDEX to 0 and try running it again.
  // And then, check the list of the ports,
  // find the port "/dev/cu.usbmodem----" or "/dev/tty.usbmodem----" 
  // and replace PORT_INDEX above with the index number of the port.

  myPort.clear();
  // Throw out the first reading,
  // in case we started reading in the middle of a string from the sender.
  myString = myPort.readStringUntil( 5 );  // 10 = '\n'  Linefeed in ASCII
  myString = null;

  sensorValues = new int[NUM_OF_VALUES];
}



void updateSerial() {
  while (myPort.available() > 0) {
    myString = myPort.readStringUntil( 10 ); 
    if (myString != null) {
      String[] serialInArray = split(trim(myString), ",");
      if (serialInArray.length == NUM_OF_VALUES) {
        for (int i=0; i<serialInArray.length; i++) {
          sensorValues[i] = int(serialInArray[i]);
        }
      }
    }
  }
}

This is my Arduino code

// IMA NYU Shanghai
// Interaction Lab
// For sending multiple values from Arduino to Processing
void setup() {
Serial.begin(9600);
}

void loop() {
int sensor1 = analogRead(A0);
Serial.print(sensor1);
Serial.println();
delay(100);
}
