Subject: Stupid Question


I am new to this. I was wondering for this beginner circuit:

http://www.piclist.com/techref/piclist/cheapic/bincnt.htm

does the C = 33pf designate a Crystal? if not, if it is a capacitor then I
am confused by the drawing because it says 32.768 kHz but does not show an
icon for the crystal.

IT MOST CERTAINLY DOES!

Which leads me to a generic question. When designing a circuit how do you
choose which crystal to use?

What timing functions do you need in the design?  what serial
communications?

 do all projects use the same generally?

None of mine do.

 what brand and part number?

This is too much...

 Also, what other components need to be ordered (like 5v regulator, etc).

 I am going to make an order to digikey and I
dont want to get the stuff and realize I have to place a whole other order
becasue I forgot some stupid support component...
^^^^^^^

You do the COMPLETE specification and design BEFORE you order parts like
crystals etc.  You also take the time to spell check before posting, you
add [PIC] to the subject, if you want to avoid Olinisms.
