+  Example_04_Buzz_Volume
+
+  This example shows how to control the buzzer to sound at different volumes.
+
+  Note, the "on()" function accepts three arguments, and you must send all three
+  in order to access the volume control.
+
+  on(frequency, duration, volume);
+
+  It turns the buzzer on and off.
+  Much like the classic "blink LED sketch" this will buzz
+  the buzzer once every second at a different volumes.
