It is assumed that the reader knows how to connect the pins of HMCL breakout board to Arduino, which is very simple. HMCL        Arduino VCC                 -> 5V or 3.3V (HMCL is rated for 3.3v but the break out board have a small voltage regulator) GND                -> GND SDA                 -> SDA SCL                  -> SCL This header will only work for HMCL Magnetometer with I2C address of 0x1E. It is configured for single measurement each cycle. This means when the  compass_scalled_reading()  function is called, the HMCL is woken up and measurement is taken and then goes back to sleep mode. Moreover, the measurements are averaged by 8 samples and this averaging is hard coded. compass.h, require #include before #include “compass.h”, see the example file. Moreover, it also require to initialize I2C port by writing command “Wire.begin();” before calling any of the given functions.  Global Variables The header file will pass these variables as Global Variables float  bearing                                  (Angle from Magnetic North
