Here is some code to get started with the gyro. Make sure to include the gyro library and the standard Arduino wire library (the communication protocol used by the gyro). Then in the setup function start up the Wire communication and initialiaze the gyro with a scale. You can use 2000, 500, or 250. This number determines the range of the values from the gyro.

  Wire.begin();  gyro.initialize(2000);  Serial.begin(9600);

In the main loop we get X, Y, and Z orientations with the get functions, for example:

  x = gyro.getX();

Then we spit these values out on the serial port wait 300 milliseconds and repeat. See the whole example sketch and grab the library from the download section below.
