Arduino and HMC5883L
Here is the Arduino and HMC5883L chip together using the Adafruit library and some tweaking of a few other shared codes.
I figured out how to calculate the declination for my particular location. Declination can be found on a cool website located here: www.magnetic-declination.com
My particular declination is Negative West -4° 40′
Here is a small video showing the system working with visual aid so that I can really nail down how the chip works and gather as much information from it as I can for database purposes later.
