Digital Compass Info Video
Thinking about using a digital compass? Watch this video first!
If you're building an autonomous vehicle or a hand-held GPS (or any other device where direction might be important), a digital compass (sometimes called a magnetometer) is a great little sensor to add to your design. However, if you haven't played around with them much, you might not know which type of compass is good for your specific project (for example, do you need tilt-compensation?).
Check out this video we put together. Here, SparkFun Engineer Chris explains a little bit about digital compasses and helps clear up some common issues people have with them.
