I'd like to use a gyroscope to control my robot path: for example, to control if the path does not diverge from the received path.

If this occurs, i control the motors in order to follow the correct path.

I'm using a tinkerkit gyroscope with a tinkerkit shield but i'm not able to understand the outputs i read from the serial monitor.

In particular, i'm using the sample code to test the gyroscope, the same you can find on the product page:

http://store.arduino.cc/ww/index.php?main_page=product_info&cPath=16_19&products_id=180

I try to rotate or to move the gyroscope with my hands but i do not understand the output parameters, in particular roll and pitch angle.

When do they change? i try to turn the gyroscope on its axis, but parameters does not seem to change a lot.

Can you help me, please?

Calibration...
