| ButtonMouseControl | |
| For Leonardo and Due boards only. | |
| 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. | |
