Circuit diagrams

In this chapter, we will create two projects. The first project will use the L298 motor driver to control a single motor and the second project will use the L293D chip to control a single motor. Here is the circuit diagram for the L298 motor driver project:

Before we explain this diagram, let's look at the circuit diagram for the L293D chip circuit as well because there are a lot of similarities between these two diagrams:

The first thing to note with these two diagrams is the circuits contain a common ground. What this means ...
