Connecting a Switch and an LED
Enough theory! It's time to wire up the components. For the example, you're using a switch
that incorporates an LED, but you could use a separate LED and switch. You will wire them
up as shown in Figure 1-8.

Making Connections
There are a variety of ways to join wires and components together. Figures 1-9 through 1-12
show different ways of making connections. Important considerations are that the joint is
secure and that you have a good connection; otherwise, the joint will create a high resis-
tance or come apart.
