Hi everyone,

I'm new to PCB layout but I'm trying to put my simple circuit on a PCB. I downloaded eagle and the arduino serial single ended file. I found the file impossible to work since the parts are not aligned to the 0.1" grids. How do I realign the parts? Should be easy but I can't find it. Any quick tips? Thanks. I just need bare minimal ardino with crystal so it should be easy except I have a bit of learning curve. Thanks.
BTW, is the single-sided arduino serial board metric? That would explain why the positions won't fit on my inch spacing.

Better to change your "grid" settings until it works for you than to move all the components around...  The original Arduino is just "off grid"; the board partially because it's very common to move components to finer positions to tighten things up, and partially "other";  I've never quite figured out why the schematic is off-grid...

There are "ULPs" that will put the components on-grid for you
"run cmd-snap-board"  for the board (which will make quite a mess!) and
"run snap-on-grid-sch" for the schematic, which seems to work pretty well.

Eagle may start up with a funky grid - press F10 for .05" grid

To move individual components to grid . . .
Move tool, select component, CTRL, left click 2x

westfw and sparks, thanks a lot. I will try more. Actually all I want is a bare system on a pcb. Then the arduio pins will line up with a 16x2 LCD's pins. This should not take much time but I'm noob.

Sparks you are a legend, didnt know about the CTRL + 2x left click :D
