What I want to do is opening a second window and closing it, then repeating this.

I succeeded in opening(by pressing a button) and closing once. If I want to open the same window again, how can I do this?

I'm trying to use PFrame or controlP5.

IF statement doesn't work (using Arduino, Firmata, controlP5)

I'm using Processing 1.5.1 on a Windows7-64bit machine.
2. import controlP5.*;
3. import processing.serial.*;
4. import cc.arduino.*;
6. Arduino arduino;
7. ControlP5 cp5;
9. int ledPin = 12;
10. color mycolor = color(0);
11. int sliderValue = 100;
12. boolean sliderValueLargetThanHundred = false;
14. void setup() {
15. arduino = new Arduino(this, Arduino.list()[0], 57600);
16. arduino.pinMode(ledPin, Arduino.OUTPUT);
18. size(700, 400);
19. cp5 = new ControlP5(this);
21. cp5.addSlider("sliderValue")
22. .setPosition(20, 200)
23. .setRange(0,255)
24. .setSize(255, 20)
25. .setValue(100)
26. ;
27. }
29. void draw() {
30. background(mycolor);
32. if(sliderValue > 100) arduino.digitalWrite(ledPin, Arduino.HIGH);
33. else arduino.digitalWrite(ledPin, Arduino.LOW);
34. }
36. public void sliderValue(int value) {
37. sliderValueLargetThanHundred = value > 100;
38. }
When I run this code, even if i change sliderValue by dragging slider, there is no change to the LED connected to Arduino board.

If I use a boolean variable(sliderValueLargerThanHundred) instead of "sliderValue > 100", the light is turned on and off as I expected.

Why does that IF statement only works with a boolean variable?
