7.1 The Breadboard
Breadboards are one of the most fundamental pieces when learning how to build circuits. In this tutorial, we
will introduce you to what breadboards are and how they work.
Let us look at a larger, more typical breadboard. Aside from the horizontal rows, breadboards have what are
called
power rails that run vertically along the sides.
Power rails.
