-/* 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.
