Hello, I am very new to processing and I need some help. I am trying to send information from Arduino that writes it to serial when a button pushed.Processing is reading information from serial and playing one of the movies. Before I push any buttons it plays sound of all the movies I have. Could you tell me what is wrong with my code or if there is another way to do it.
Thank you.




// importing the processing serial class

import processing.serial.*;
import processing.video.*;

Movie  myMovieT, myMovieA;

// definition of window size and framerate
 int xWidth = 768;
 int yHeight = 512;
 int fr = 24;
 int xsp,ysp,xspeed;
 

 
// variables for serial connection, portname and baudrate have to be set
 Serial port;
 String portname = "/dev/tty.usbserial-A9003XAq";
 int baudrate = 9600;
 int value = 0;
 String buf="";
 


void setup(){
 // set size and framerate
 port = new Serial(this, portname, baudrate);
 size(xWidth, yHeight); frameRate(fr);
 background(0);

 myMovieT = new Movie(this, "movie2.mov");
 myMovieA = new Movie(this, "movie3.mov");


myMovieT.stop();
myMovieA.stop();
 }


void serialEvent(int serial){
 
    if(serial == 'G') {  
    myMovieA.stop();
      myMovieT.play();
   image(myMovieT, 0, 0);
    println("Ted");
   } else if(serial == 'I') {  
    myMovieT.stop();
     myMovieA.play();
   image(myMovieA, 0, 0);    
     println("Susan");
       }
         
}

// draw listens to serial port, draw
void draw(){
// listen to serial port and trigger serial event  
 while(port.available() > 0){
  value = port.read();
  serialEvent(value);
  }
 
   
      myMovieA.read();
       myMovieT.read();
