Thanks everyone for all the replies!
It ended up being a much dummer problem. I just needed to set Arduino software to Lilypad (it was to Duemilanove).
Also, I've altered the example with accelerometers that comes within Arduino's default examples.
I've mixed it with this code by Chris from Robot is Happy (Management System), and I was able to communicate and test my Lilypad connected to a simple 3-axis accelerometer with the following code:
import processing.serial.;
import processing.opengl.;
Serial myPort;
int baudRate = 9600;
int lf = 10;
PFont font;
int[] xAxis;
int[] yAxis;
int[] zAxis;
int currentX = 0;
int currentY = 0;
int currentZ = 0;
//these value were determined by taking readings from a resting position
int oneGSensorValue = 400;
float oneGMillivolt = oneGSensorValue * 4.9;
int totalReadings = 800;
int readingPos = 0; // the reading position in the array
void setup(){
-
smooth();*
-
size(800, 500, OPENGL);*
-
font = createFont(PFont.list()[270], 24);*
-
smallFont();*
-
xAxis = new int[totalReadings];*
-
yAxis = new int[totalReadings];*
-
zAxis = new int[totalReadings];*
-
for (int i=0; i < totalReadings; i++){*
_ xAxis = oneGSensorValue;_
_ yAxis = oneGSensorValue;
zAxis = oneGSensorValue;
