Processing to control Arduino via Firmata

Hi all, I'm trying out a simple program to find out how Processing works in controlling an Arduino board using Firmata.
- import processing.serial.*;
- import cc.arduino.*;
- //input pin for button 1
- int button1Pin = 2;
- //output pin for LED 1
- int button1LED = 13;
- int buttonState = 0;
- Arduino arduino;
- void setup()
- {
- arduino = new Arduino(this,Arduino.list()[2],9600);
- arduino.pinMode(button1Pin,Arduino.INPUT);
- arduino.pinMode(button1LED,Arduino.OUTPUT);
- println(Arduino.list());
- }
- void draw()
- {
- buttonState = arduino.digitalRead(button1Pin);
- if(buttonState == Arduino.HIGH)
- {
- arduino.digitalWrite(button1LED,Arduino.HIGH);
- println("button1 is HIGH");
- }
- else
- {
- arduino.digitalWrite(button1LED,Arduino.LOW);
- println("button1 is LOW");
- }
- }
This is the Processing sketch. It can run without errors, but it doesn't seem to take any input from the button.
On the Arduino side, I uploaded the StandardFirmata sketch.
Is this correct or do I need to do other coding on the Arduino sketch as well?
