I am just getting started with Arduino...I figure this is kind of a newbie question but here goes.
I have a Duemilanove and the Sparkfun Speakjet shield. I've got some breakaway headers (not the stackable headers) for connecting the Duemilanove with the Speakjet shield. But then I want to interface a bunch of other stuff like switches and LEDs to the Arduino pins that are not used by the Speakjet shield.
Is it required to get the stackable headers to wire up my switches and LEDs to the Arduino pins? Or is it advisable to just solder wires for my switches and LEDs onto the tiny nubs of the breakaway headers where they poke through the top of the Speakjet shield?
