if I can understand well informations & data flows, I have a big newbie problem in my head: power supply  Embarrassed  Grin

on http://www.wiring.org.co/learning/tutorials/diagrams.html  , I can see that components can be powered by the VCC pin 5V.

if I use usb to power the board, can I use VCC pin to power some components?
how many components can i power like that ? the real question is, how can i calculate that?
