  1. /* Basic USB Joystick Example
  2. Teensy becomes a USB joystick
  3.  
  4. You must select Joystick from the "Tools > USB Type" menu
  5.  
  6. Pushbuttons should be connected to digital pins 0 and 1.
  7. Wire each button between the digital pin and ground.
  8. Potentiometers should be connected to analog inputs 0 to 1.

  10. This example code is in the public domain.
