TheChrisyd 2:20a89dc286d5 27 Notes
TheChrisyd 2:20a89dc286d5 28 -----
TheChrisyd 2:20a89dc286d5 29 To specify an analog pin for a button add "A0" to
TheChrisyd 2:20a89dc286d5 30 the pin number, eg. Analog pin 4 is "A0+4"
TheChrisyd 2:20a89dc286d5 31
TheChrisyd 2:20a89dc286d5 32 When connecting a Joystick to an Arduino:
TheChrisyd 2:20a89dc286d5 33 * Digital pins 0/1 are used for system stuff.
TheChrisyd 2:20a89dc286d5 34 * Gameduino uses pins 2/9/10/11/13 for SPI interface
TheChrisyd 2:20a89dc286d5 35
TheChrisyd 2:20a89dc286d5 36 That leaves digital pins 3/4/5/6/7/8/10 free, plus
TheChrisyd 2:20a89dc286d5 37 all the analog pins (which work as digital pins, too!)
