Recitation 10–Vivien Hao

For this recitation, I chose to do the media one. I have a lot of videos from different concerts. I have chosen one video and then insert it in this code. I want to use the videos that I have taken in the past. And by using potentiometer, I could control the speed of the video. The following codes are for Arduino and Processing. 

Arduino:

// 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);
}

Processing:

import processing.video.*;
Movie myMovie;
import processing.serial.*;
Serial myPort;
int valueFromArduino;

void setup() {
  size(400, 400);
  myMovie = new Movie(this, "ljj.mp4");
  myMovie.play();
   printArray(Serial.list());
  // this prints out the list of all available serial ports on your computer.

  myPort = new Serial(this, Serial.list()[ 2 ], 9600);
  //define the state of the video
}
void draw() {
  while ( myPort.available() > 0) {
    valueFromArduino = myPort.read();
  }
  println(valueFromArduino);
  float x = map(valueFromArduino,0,1023,0,93);
  if (myMovie.available()) {
    //read my file when it can be read
    myMovie.read();
    //read the current frame of the video
  }
  //draw the frame
  if (mousePressed){
   if (mouseX<width/2){
     myMovie.jump(myMovie.time()-x);
     myMovie.read();
   }else{
     myMovie.jump(myMovie.time()+x);
     myMovie.read();
   }
  }
  image(myMovie, 0, 0);
}
