Expanded the introduction to piezo buzzers to explain that there are two types with slightly different uses. It is important that the student/user be using an active buzzer for the example code to work.
Added text stating that a passive piezo buzzer could be used as an alternative to a speaker and updated the warning to say that active piezo buzzers shouldn't be used.

Removed unintentionally added whitespace.
