Yes, only purpose for a bread board is to experiment with additional
hardware. The bread boards meant to go with the raspberrypi have a cable
that connects between the i/o pins on the pi and a "breakout" board that
provides logical locations for the various PI power and i/o pins.
If you don't care to add hardware that needs more i/o access than the
built-in ports, you can ignore all the breadboard stuff.

Hey guys,===========================================================
Thanks for the info. It sounds like this is another common challenge that
all newbies face, and unfortunately nobody has cooked up a workaround yet.
In my case, it's not so much navigating the board; as others have said that
could be done by space-counting or marking the area somehow. The problem
comes with making sure all the pieces I'm connecting to it are in the right
place. For example, my kit came with an LED light (four wires) a stepper
motor (3-4 wires) and a bunch of other gizmos I haven't learned by name yet
with 3-4 wires, and it seems all these have to be plugged into very
specific cells on the breadboard. But these wires are extremely short, so
it's not like I can go one at a time like with either ends of a resistor.
With resistors I used the one end for space-counting like someone suggested
using a stylus. But with these things that have multiple wires to connect
that isn't as straightforward. I could get the far left wire of the LED
into the right hole, but it was hard to tell if the other 3 were even in
the holes.
But let me take a step back and ask a newbie question here: what exactly is
the purpose of a breadboard? I read where one of you said you never used
one before, so it sounds like you can work with the Pi/Arduino without
having to mess with them. From what I've read on Google, it sounds like
they are just for experimenting, so I'm kind of wondering what else there
is.
Anyway, thanks again and have an awesome weekend. :)

So is there such a thing as a breadboard with better spacing between
