This is a guide to using the motors and sensors from the lego nxt set with a parallax basic stamp ii or bs2.
Nxt compass sensor tutorial.
Some of these movies have exercises directly under them.
Using the hitechnic compass sensor with nxt g.
In the picture to the left you can see the compass sensor is mounted high well above both the motors and computer brick.
A brief introduction tutorial part 2 duration.
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.
Using nxt components with a micro controller.

I think this is a limit of the nxt g interface not the sensor itself.
It needs a hitechnic or mindsensors compass sensor plugged in to one of the sensor ports.
Program using labview lego.
Put a compass equiped ro bot on a turntable and spin the turntable.
The current heading is calculated to the nearest 1 and refreshed 100 times per second.
The compass sensor connects to an nxt sensor port using a standard nxt wire and uses the digital i2c communications protocol.
It s important to do these exercises not just assume you get it the advanced section is for reference purposes.
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 compasspilot is an extension of the differentialpilot class.
To use the compass sensor from nxt g an additional piece of software needs to have been added to your computer.
The essentials are things every nxt programmer should know.
The current heading is calculated to the nearest 1 and refreshed 100 times per second.
But if you are using a port splitter or a remote nxt or rcx it may be of interest.
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.
This tutorial for lego mindstorms nxt is divided in two sections.
Using hitech compass sensor.
The nxt compass sensor contains a digital magnetic compass that measures the earth s magnetic field and calculates a heading angle.
The compass sensor connects to an nxt sensor port using a standard nxt wire and uses the digital i2c communications protocol.
The compass sensor is housed in a standard mindstorms sensor housing to match the other mindstorms elements.
The nxt sensor ports support three different types of sensor.
