+  ButtonMouseControl
+
+  Controls the mouse from five pushbuttons on an Arduino Leonardo, Micro or Due.
+
+  Hardware:
+  - five pushbuttons attached to D12, D13, D14, D15, D0
+
+  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.
