Referring to your LED connection between cells D47 and D50....
1. To be of any utility, the LED must be connected between two differing
voltages.
2. So, if the breadboard is in front of you, presumably of the standard
rectangular form,
It must have its central blank ridge running from left to right.
The hidden conductors which make the breadboard so useful are arranged in a
vertical direction, and in this example columns 47 and 50 are to be linked by
the diode (the body of which skips over the cell holes 48 and 49.
All this drama takes place on row D, the 4th row down on the breadboard.
To recap;
1) the breadboard is split, horizontally, into identical halves. This is
historical, used to suit DIL ( Double In-Line ) chips.
2)Each half is populated by a large number of independent columns, of
single holes, connected by a hidden strip and each hole is
available to plug a wire or component into .
1. Warning. There are two non-standard rows of holes at both the top and
bottom edges of the breadboard. These are for advanced power supply
arrangements. AVOID.
2. It is harmless to connect two points of equal voltage, that is, any two
holes on the same column. It is also harmless to connect any two rows, which
you won`t use for any other purpose, so that, using standard single core
insulated wire, you can make a square shaped enclosure and effectively make a
smaller and more easily manageable working space. You could possibly mark (peg)
and rename the bottom left corner (0,0), for instance.
All this becomes very much easier to manage if the breadboard and its
accessories are fixed to a work surface.

Subject: [raspberry-vi] Re: Alternative to breadboards?
Hey guys, happy TGIF!
Just to clarify, I've been using the breadboard primarily with the Arduino
for now. Like Jeffrey, my experience with computers and computer science
has been primarily on the code side of things. And my work with the Pi has
been very similar to his; all hooking up has been via USB, and I haven't
used any of its hardware capabilities beyond as a min-PC. But I've been
wanting to learn the hardware side of things, because if I can get to where
I know what I'm doing, or at the very least know the basics, I could take
it to the next level by hooking stuff up to the Pi.
But with that said, I really like the toothpick idea! Not just for
space-counting, but for marking where stuff should go. For example, the
tutorials I'm following now have you plugging an RGB LED into cells D47 to
D50 (I may be off on that) of the breadboard. So if I put toothpicks on
i.e. D45 and D51, that might help me confirm that the four wires fit neatly
between the two. So far, that seems to be the best solution I've heard
(sorry, I didn't get the whole fish bone corral thing, LOL). Anyway, I
sure appreciate all your patience and awesome suggestions.
Anyway, let me ask you this: what do the "cells" represent? I've been
using Excel terminology because that's the best thing I can compare it to.
It has letters and numbers, and I bet they all mean something.

I would be very reluctant to poke around with a conductive wire. The
Raspberry- Pi is very sensitive to mis-connection or the shorting
together
of adjacent points.
This is in comparison to the Arduino, for instance, which is much tougher.
Ok, you say, you ALWAYS SWITCH OFF before making tests..... ...... Always?
I generally advise that the breadboard, along with the processor board,
should be firmly located on a decent sized tray capable of supporting the
wrist while you are picking along the rows of holes.

Mike,
As for breadboards, I use a a wire to count holes. It is not efficient but
kind of works.
