problem connecting arduino using serial port

edited March 2018 in Arduino

Hallo. My name is davide, i using processing by only 2 day. i have some problem to connect arduino with my processing code, it work but it's very slow. I control led's luminosity using PWM, (the PWM value is given by processing soft) but the time between i select the value in the soft and i see luminosity changing it's around one second (it's too much). I don't understand why.... (wich is the code command???) the code is:

import processing.serial.*;
Serial arduino;

rotore r1=new rotore("pinza");
rotore r2=new rotore(400,180,#001CBC,#E00029,"rotazione");
rotore r3=new rotore(130,500,#087708,#CB8AD1,"spalla");
rotore r4=new rotore(400,500,#FFBB00,#00F4D8,"gomito");
void setup(){
  size(700,700);
  arduino= new Serial(this, "COM3", 9600);
  r1.disegna();
  r2.disegna();
  r3.disegna();
 r4.disegna();
 }
void mousePressed(){
  r1.muovi();
  String valore=String.valueOf(r1.angolo()+1000);
  if(r1.dentro()==true){
    arduino.write(valore);
  }
  r2.muovi();
  valore=String.valueOf(r2.angolo()+2000);
  if(r2.dentro()==true){
    arduino.write(valore);
 }
  r3.muovi();
  valore=String.valueOf(r3.angolo()+3000);
 if(r3.dentro()==true){
    arduino.write(valore);
  }
 r4.muovi();
}
void draw(){}

    What is your definition of rotore()? I can see this is your own definition. Is there some code that you forgot to include in your post?

    Arduino waits one second to wait the end of string. i solved sending an empty string after the first string....

    void mousePressed(){
  r1.muovi();
  String valore=String.valueOf(r1.angolo()+1000);
  if(r1.dentro()==true){
    arduino.write(valore);
    arduino.write(" ");
  }

    i have again some problems.

    import processing.serial.*;

    the code works the firs command and didn't work if i gave a second comand, but it wors at the tird command and didn't work at the fourth. pratically it works only on the odd commands. class declaration on the bottom. i don't understand were is the error....
