Joystick - dtex/johnny-five GitHub Wiki

The Joystick class constructs objects that represent a single Joystick sensor attached to the physical board.

This list will continue to be updated as more Joystick devices are confirmed.

• General Options

  Property	Type	Value/Description	Default	Required
  pins	Array of Pins	["A*", ...]. Analog pins connected to X and Y		yes
  invert	Boolean	true, false. Invert both axes	false	no
  invertX	Boolean	true, false. Invert the X axis	false	no
  invertY	Boolean	true, false. Invert the Y axis	false	no

new five.Joystick({
  // [ x, y ]
  pins: ["A0", "A1"]
});

new five.Joystick({
  pins: ["A0", "A1"], 
  invertY: true
});

new five.Joystick({
  controller: "ESPLORA"
});

var joy = new Joystick({ pins: ["A0", "A1"], invertY: true });

Produces the following default axes:

    -1
-1   *   1
     1      

var joy = new Joystick({ pins: ["A0", "A1"], invertY: true });

Produces an inverted Y axis, with a default X axis:

     1
-1   *   1
    -1      

var joy = new Joystick({ pins: ["A0", "A1"], invertX: true });

Produces an inverted X axis, with a default Y axis:

   -1
1   *  -1
    1      

var joy = new Joystick({ pins: ["A0", "A1"], invert: true });

Produces an both inverted X and Y axes:

    1
1   *  -1
   -1      

There are no special API functions for this class.

• change The "change" event is emitted whenever the value of an axis changes.

• data The "data" event is fired as frequently as the user defined freq will allow in milliseconds.
