Hi guys!
Here it is something that i write to try, a simple hello world of computer vision. I use roborealm, (a GUI video processing and computer vision software). I receive data with processing from a txt file (ok working) where i save with roborealm variable values, i use it for an if (ok working) i use tts to sintetyze speech (ok working) and I want to use arduino library to change a digital pin state from low to high...
in arduino code i have an if that calls a function of servo steering if state is HIGH. But this  don't works, my problem is here...

processing code:
Code:

import cc.arduino.*;
import guru.ttslib.*;
import processing.serial.*;
int data = 0;
int comPin = 3;
int perception = 0;
int something = 0;
Serial Serial;		   
Arduino arduino;
TTS tts;


void setup() {
  /*String portName = Serial.list()[0];
  Serial = new Serial(this, portName, 9600);*/
  arduino = new Arduino(this, Arduino.list()[0], 57600);
  arduino.pinMode(comPin, Arduino.OUTPUT);
  tts = new TTS();
  println(Serial.list());
  size(200, 200);
  background(200);
  stroke(255);
  frameRate(2);
}

void draw() { 
 /* 
  data = Serial.read();
  if (data == 'A') {
    tts.speak("Oh my god! I am alive!");
    tts.speak("Why?!");
    delay(200);
  }
   if ( data == 'B') {
    tts.speak("Lets go I want to understand something");
    delay(200);
  }
  if (data == 'C') {
    tts.speak("crappity smacking obstacle");
    delay(200);
  }
  */
   String[] lines = loadStrings("cogx.txt");
   if (lines.length == 2) {
   int[] nums = int(split(lines[0], ';'));
   int detect = nums[0] + nums[1] - 640;
   int focus = nums[0] + nums[2] - 640; 
   if (focus < random( 220, 400)) {
   arduino.digitalWrite(comPin, arduino.HIGH);
   tts.speak("Oh");
   delay(200);
   tts.speak("I got something");
   delay (400);
   arduino.digitalWrite(comPin, arduino.LOW);
   
}
}
}
 

arduino code:
Code:

void receiver() {
int state = digitalRead(comPin);
if (state == HIGH) {
flip();
digitalwrite(comPin, LOW);
} 

My problem is also that i use serial communication (that is commented) in processing code to receive  calls from arduino to say sentences of ttslib. My problem is that arduino library and serial don't works toghether, i think I have to use one of theese. But serial.write on arduino code don't work properly, i tried to send letters, numbers...but it seems that processing don't take it
