Run Your Program
Slowly spin your Spatial Phidget on your desk. You will see a Compass Heading being printed to the screen. This value ranges from 0 to ±180 degrees. When you are within 10 degrees of a cardinal direction (N,E,S,W) your program will print the direction it is pointing.
The Compass Heading is aligned with the top of your Spatial Phidget (shown above).
Practice
- Modify your code to print the ordinal directions (NE, NW, SE, SW)
- Create a GUI and point an arrow in the direction your Spatial Phidget is pointing.
