/*
  Esplora Joystick Mouse

 This  sketch shows you how to read the joystick and use it to control the movement
 of the cursor on your computer.  You're making your Esplora into a mouse!

 WARNING: this sketch will take over your mouse movement. If you lose control
 of your mouse do the following:
 1) unplug the Esplora.
 2) open the EsploraBlink sketch
 3) hold the reset button down while plugging your Esplora back in
 4) while holding reset, click "Upload"
 5) when you see the message "Done compiling", release the reset button.

 This will stop your Esplora from controlling your mouse while you upload a sketch
 that doesn't take control of the mouse.
