+  ButtonMouseControl
+
+  For native USB boards (e.g., Leonardo, Micro, MKR, Nano 33 IoT, Zero, Due) only.
+
+  Controls the mouse from five pushbuttons.
+
+  Hardware:
+  - five pushbuttons attached to D2, D3, D4, D5, D6
+
+  The mouse movement is always relative. This sketch reads four pushbuttons,
+  and uses them to set the movement of the mouse.
+
+  WARNING: When you use the Mouse.move() command, the Arduino takes over your
+  mouse! Make sure you have control before you use the mouse commands.
+

+const int upButton = 2;
+const int downButton = 3;

+  int  yDistance = (upState - downState) * range;
+
