goatfish, Eagle is what I use to turn schematics into PCBs.

That schematic you posted was made in Eagle.

I actually did it in Microsoft Visio which, with Acrobat Professional, then allowed me to save it as a PDF including all the 'layers'.

Yeah quite right - but you won't be able to do it from my PDF - of course. This would mean having to re-create the circuit in Eagle - and perhaps someone may do this and contribute it to the community. Eagle is great for going to PCB but has no option, as I understand it, to come up with a layout on matrix board or strip board. Given that most beginners will be using that format then thats why I choose the sledgehammer approach to create a matrix board layout using whatever 'drawing' tools I had available.

Give me a few hours and I'll knock together an Eagle 5 schematic - which would then help to produce your PCB design.

oh thank-you so much  ;D ;D ;D ;D :D :D :D :D :) :) :) ;) ;),i look forward to seeing that,i tried to make the board in eagle but it wouldn't let me auto-route it,because its the lite edition

newbie:
i followed this schematic pdf, i found some problem:
1. is the 4xAA battery pack for the servo output?
2. is the 9v pp3 battery for the microcontroller?

i found the voltage at the servo output is lower than the voltage at sensor input, why? is this correct?

The lite edition can do autoroute.

The only thing it can't do is really large boards, and more than 2 layers.
