If we don't use a couple pads (next to R2, C12), then we should probably make note of that, since I got very confused when some pictures used those pads, and others didn't. tno 09:14, 25 April 2010 (UTC)

AGND-GND solderingbridge

Hi Thenoviceoof, this AGND-GND solderingbridge you mentioned is mandatory to use the analouge pins from the Atmega.
If this is not closed the Atmega behave very strange when you use the POT at pin A0,
like putting all outputs at 2,5V etc. At this state you can't program or use the Atmega correctly.

Kind regards,
