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.
