You discover how to use your Python programming skills to sense what is happening in the outside world and to control lights, motors, and in fact anything else that uses electricity. However, before you can do this safely, without risking damage to you or your Pi, you need to look at a little bit of background electrical theory, so you have a foundation to build on.
In this chapter, we show you the relevant concepts that allow you to understand why the projects look like they do and what you should avoid doing.
