Some of these movies have exercises directly under them.
Nxt compass sensor tutorial.
However rather than just providing schematics and sample code for the bs2 i ll be providing some theory on how the sensors work as well.
If you are using a sensor connected directly to a nxt sensor port you can use the sensorport class and you can probably skip this section.
The current heading is calculated to the nearest 1 and refreshed 100 times per second.
This is a guide to using the motors and sensors from the lego nxt set with a parallax basic stamp ii or bs2.
I think this is a limit of the nxt g interface not the sensor itself.
It s important to do these exercises not just assume you get it the advanced section is for reference purposes.
