Unwire everything, check if the port COM is correct, plug usb and reup.

If u got the same error, reinstall arduino board or try it on a different pc.

Hoping isn't the board.

I really need to know if is possible to solve this problem:
I have some sensors attacched on analog inputs on an arduino duemilaenneove board. Inputs read works fine, but sometimes i need to know when a sensor is unplugged, so i

unplugged one and the result is:

I don't understand why voltage isn't 0 when I have no input on the port.
I can fix that using a range of accepted values, but with a 0 value  is easier.

Is it a mine mistake?  :'(  :-?
