Preparing the Breadboard
In the center of the PDB is a solderless breadboard where we will build circuits that
are not integral to the PDB lab board itself (a variety of components are included in
the StampWorks kit). It’s important to understand how this breadboard works. With
a little bit of preparation, it will be even easier to use with the experiments that
follow.
The innermost portion of the breadboard is where we will connect the components.
This section of the breadboard consists of several columns of sockets (there are
numbers printed along the top for reference). For each column there are two sets of
rows. The rows are labeled A through E and F through J, respectively. For any
column, sockets A through E are electrically connected. The same holds true for
rows F through J.
Above and below the main section of breadboard are two horizontal rows of sockets,
each divided in the center. These horizontal rows (often called “rails” or “buses”) will
be used to carry +5 volts (Vdd) and Ground (Vss).
The preparation of the
breadboard involves connecting the rails so that they run from end-to-end,
connecting the top and bottom rails together and, finally, connecting the rails to the
Vdd and Vss connections of the PDB power supply. Here’s what the breadboard
looks like on the outside:
