Arduino Keyboard and Mouse Control Code

This example illustrates the use of the Mouse and keyboard libraries together. Five momentary switches act as directional buttons for your cursor. When a button is pressed, the cursor on your screen will move, and a keypress will be sent to the computer. Once you have the Leonardo programmed and wired up, open up your favorite text editor to see the results.

NB: When you use these libraries, the Arduino takes over your computer’s keyboard and mouse!

Software Required

Code

/*
KeyboardAndMouseControl

Controls the mouse from five pushbuttons on an Arduino Leonardo or Micro.

Hardware:
* 5 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.
