Lesson 11: Making sounds
Overview
In this lesson, you will learn how to make sounds with your Arduino. First you will make the
Arduino play a 'musical' scale and then combine this with a photocell, to make a Theremin-
like instrument that changes the pitch played as you wave your hand over the photocell.
