Digital compass shows angle and direction on LCD display.

Digital Compass with LCD

The digital compass sends the heading to Arduino which then elaborates the data, providing the result in degrees and direction (i.e. N,S,W,E) through serial USB and the LCD display. The potentiometer controls the LCD contrast.
