We’re reviewing this to help you when we hook up the components in the next two sections.
The above diagram is a representation of a breadboard as seen from the top and seeing through the plastic.
Notice the holes — these are the holes in which the jumpers are pushed, and are made of metal in order to conduct electricity (act as channels for the electricity).
Notice that across the bottoms of the holes, along the rows, are flat wires — these connect the five holes in each row to each other (acting as channels for the electricity).
Note that the columns are not connected (so there can be no flow between columns unless you add a jumper between the holes in different columns).
Take a look at see the diagram from the previous module, and see if you can see how it lines up with the new diagram.
