Music with a Piezoelectric Buzzer

In this project, we will be generating sound using a piezoelectric buzzer. We will initially explore how to generate different frequencies by cycling a digital pin from HIGH to LOW at different rates. We will then examine some of the fundamentals of music theory and how they can help us play music with our buzzer.
