 * 

 * Compass.ino - Example sketch for reading a heading from an HMC5883L triple axis magnetometer.

 * 

 * GY-273 Compass Module  ->  Arduino

 * VCC  -> VCC  (See Note Below)

 * GND  -> GND

 * SCL  -> A5/SCL, (Use Pin 21 on the Arduino Mega)

 * SDA  -> A4/SDA, (Use Pin 20 on the Arduino Mega)

 * DRDY -> Not Connected (in this example)

 * 

 * Voltage Note

 * ~~~~~~~~~~~~  

 * The GY-273 Board has a 3v3 Regulator on it, and the SDA/SCL are pulled up to that so it is OK to 

 * use with 5v Arduino's.

 * 

 * If you are using any other breakout, or the raw IC, you need to be using 3v3 to supply and signal!

  // Magnetic Declination is the correction applied according to your present location

  // in order to get True North from Magnetic North, it varies from place to place.

  // 

  // The declination for your area can be obtained from http://www.magnetic-declination.com/

  // Take the "Magnetic Declination" line that it gives you in the information, 

  //

  // Examples:

  //   Christchurch, 23° 35' EAST

  //   Wellington  , 22° 14' EAST

  //   Dunedin     , 25° 8'  EAST

  //   Auckland    , 19° 30' EAST

  //    

  Compass.SetDeclination(-0, 23, 'W');  

  // The device can operate in SINGLE (default) or CONTINUOUS mode

  //   SINGLE simply means that it takes a reading when you request one

  //   CONTINUOUS means that it is always taking readings

  // for most purposes, SINGLE is what you want.

  Compass.SetSamplingMode(COMPASS_SINGLE);

  // The scale can be adjusted to one of several levels, you can probably leave it at the default.

  // Essentially this controls how sensitive the device is.

  //   Options are 088, 130 (default), 190, 250, 400, 470, 560, 810

  // Specify the option as COMPASS_SCALE_xxx

  // Lower values are more sensitive, higher values are less sensitive.

  // The default is probably just fine, it works for me.  If it seems very noisy

  // (jumping around), incrase the scale to a higher one.

  Compass.SetScale(COMPASS_SCALE_130);

  // The compass has 3 axes, but two of them must be close to parallel to the earth's surface to read it, 

  // (we do not compensate for tilt, that's a complicated thing) - just like a real compass has a floating 

  // needle you can imagine the digital compass does too.

  //

  // To allow you to mount the compass in different ways you can specify the orientation:

  //   COMPASS_HORIZONTAL_X_NORTH (default), the compass is oriented horizontally, top-side up. when pointing North the X silkscreen arrow will point North

  //   COMPASS_HORIZONTAL_Y_NORTH, top-side up, Y is the needle,when pointing North the Y silkscreen arrow will point North

  //   COMPASS_VERTICAL_X_EAST,    vertically mounted (tall) looking at the top side, when facing North the X silkscreen arrow will point East

  //   COMPASS_VERTICAL_Y_WEST,    vertically mounted (wide) looking at the top side, when facing North the Y silkscreen arrow will point West  

  Compass.SetOrientation(COMPASS_HORIZONTAL_X_NORTH);

}

// Our main program loop.

   float heading = Compass.GetHeadingDegrees();
