+  KeyboardAndMouseControl
+
+  Controls the mouse from five pushbuttons on an Arduino Leonardo, Micro or Due.
+
+  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.
