+/* Robot Inputs
+
+ This sketch shows you how to use the on-board 
+ potentiometer and buttons as inputs. 
+
+ Turning the potentiometer draws a clock-shaped 
+ circle. The up and down buttons change the pitch, 
+ while the left and right buttons change the tempo. 
+ The middle button resets tempo and pitch.
