    DIY Digital Compass (for your car)

    I am attempting to do this without using the OLED output. I also do not need a logic converter because my USB arduino is 3.3V. So if I just exclude these two components, will the compass operate properly? And does a serial output simply mean it will print in the Arduino program if the compass is connected to my laptop?
