Creating a diagram

Once we have defined the inputs and outputs of the circuit and the logic for the project, the next step is to diagram the circuits. We will want to make sure that we diagram all of the circuits that we create even the most basic ones. This will help us figure out resistors needed and to visualize how we want to organize and connect the component.

When creating the circuit diagrams, I would recommend using the Fritzing software that was described in Chapter 3, Circuit Diagrams. Now let's look at the final step, building the prototype.
