Digital Compass using Arduino and HMC5883L Magnetometer

Since the sensor could indicate the geo-graphic North, South, East and West, we humans could also use it at times when required. So in this article let us try to understand how Magnetometer sensor works and how to interface it with a microcontroller like Arduino. Here we will build a cool Digital Co...
