avrdude: Device signature = 0x000000 avrdude: Yikes! Invalid device signature. Double check connections and try again, or use -F to override this check.

This is the clue to the solution. The signature is different between different versions of the ATmega328, example:

• ATmega328-PU
• ATmega328P-PU

and so on...

You can google on "arduino signature error ATmega328P" to find the solution.

One hint is: http://forum.arduino.cc/index.php?topic=201920.0

I can be more specific if you post the version off the ATmega328 you have.
