In Fritzing, you can zoom in on the schematic and check your wiring. In the zoomed-in
section shown in
Figure 9-12
, you can see the pin labels on the L293D. You also can see I
left a
V+
pin unattached. This is the sort of error that's easier to catch in the schematic view
than the diagram view.

You might find that you want to create your design in a more advanced design tool, perhaps
because it has the library components you desire, it integrates better with other tools you
are using, or it has some other feature (such as simulation) of which you'd like to take ad-
vantage.
