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.
Nxt compass sensor tutorial.
The current heading is calculated to the nearest 1 and refreshed 100 times per second.
Since the us sensor block returns only a single byte the sensor returns the heading angle divided by two currently.
The current heading is calculated to the nearest 1 and refreshed 100 times per second.
Using nxt components with a micro controller.
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.
The compasspilot is an extension of the differentialpilot class.
Some of these movies have exercises directly under them.
Using hitech compass sensor.
Put a compass equiped ro bot on a turntable and spin the turntable.
Using the hitechnic compass sensor with nxt g.
It implements the same methods but uses a compass sensor to ensure that the pilot does not deviate from the correct angle of robot heading.
A brief introduction tutorial part 2 duration.
At brickfest there was a wonderful demo of the compass sensors.
It s important to do these exercises not just assume you get it the advanced section is for reference purposes.
But if you are using a port splitter or a remote nxt or rcx it may be of interest.
The compass sensor connects to an nxt sensor port using a standard nxt wire and uses the digital i2c communications protocol.
The nxt compass sensor contains a digital magnetic compass that measures the earth s magnetic field and calculates a heading angle.
In the picture to the left you can see the compass sensor is mounted high well above both the motors and computer brick.
The essentials are things every nxt programmer should know.

The nxt sensor ports support three different types of sensor.
This tutorial for lego mindstorms nxt is divided in two sections.
It needs a hitechnic or mindsensors compass sensor plugged in to one of the sensor ports.
This is a guide to using the motors and sensors from the lego nxt set with a parallax basic stamp ii or bs2.
The compass sensor is housed in a standard mindstorms sensor housing to match the other mindstorms elements.
The compass sensor connects to an nxt sensor port using a standard nxt wire and uses the digital i2c communications protocol.
I think this is a limit of the nxt g interface not the sensor itself.
