I tried searching the topics but couldn't find a good solution. I want my Arduino to blink a led for 10 times. But if I press a button in my interface it has to interrupt the while loop. But I can't click anything else because of the while loop. How can I avoid the while loop so it's possible to interrupt the blinking of the led before reaching the end of the loop?  

 

Thanks in advance.

code:

1. import controlP5.*;
   import processing.serial.*;
   import cc.arduino.*;
   Arduino arduino;
   ControlP5 controlP5;
   Button b;
   int buttonValue = 0;
   int myColor = color(0,255,180);
   boolean A = true;
   
   
   void setup() {
   size(640,480);
   smooth();
   frameRate(30);
   controlP5 = new ControlP5(this);
   controlP5.addButton("buttonA",0,100,100,80,19); 
   controlP5.addButton("buttonB",0,100,150,80,19);
   controlP5.addButton("buttonC",0,100,200,80,19); 
   arduino = new Arduino(this, Arduino.list()[0], 57600); 
   }
   
   void draw() {
   background(myColor);
   fill(buttonValue);
   rect(20,20,width-40,height-40);
   }
   
   public void controlEvent(ControlEvent theEvent) {
   println(theEvent.controller().name());
   
   }
   
   // function buttonA will receive changes from 
   // controller with name buttonA
   public void buttonA(int theValue)
   {
   int i = 0;
   
   while(i<10 && A==true ) 
   { 
   arduino.digitalWrite(13, Arduino.HIGH);
   delay(1000);
   arduino.digitalWrite(13, Arduino.LOW);
   delay(1000);
   i++;
   }
   
   
   }
   
   public void buttonB(int theValue) {
   A=false;
   }
   public void buttonC(int theValue) {
   A=true;
   }
