I need a good compass for my RWAR project (see the RC car thread…).
Anybody have any suggestions? For right now I was thinking I might just get the Parallax HMC6352: http://www.parallax.com/Store/Sensors/CompassGPS/tabid/173/CategoryID/48/List/0/SortField/0/Level/a/ProductID/596/Default.aspx
How sensitive will the compass be to the RC car’s motor?
EDIT: It’s probably worth noting that I need something pretty accurate. By how much, I don’t really know, but as long as the compass it pretty close it should be ok. I can always run a software filter on it.
