Arduino Joystick Mouse Enclosure

Enclosure for a joystick mouse made from an Arduino Pro Micro, joystick module, and tac switch. Margins are tight, so recommend lightly filing the inner tracks of the enclosure, and/or the rough sides of the boards themselves to slide them in easier. The solder points on the Arduino also need to be low profile and facing inward, and the excess solder under the joystick board needs to be clipped off.

Modified Arduino code to support right-click on pin 2:

   This is very simplistic code that allows you to turn the
   SparkFun Thumb Joystick (http://www.sparkfun.com/products/9032)
   into an HID Mouse. The select button on the joystick is set up
   as the mouse left click.
