The compass sensor is housed in a standard mindstorms sensor housing to match the other mindstorms elements.
Nxt compass sensor tutorial.
The compass sensor connects to an nxt sensor port using a standard nxt wire and uses the digital i2c communications protocol.
Some of these movies have exercises directly under them.
The compass sensor connects to an nxt sensor port using a standard nxt wire and uses the digital i2c communications protocol.
Put a compass equiped ro bot on a turntable and spin the turntable.
Using nxt components with a micro controller.
At brickfest there was a wonderful demo of the compass sensors.
This is a guide to using the motors and sensors from the lego nxt set with a parallax basic stamp ii or bs2.
The compasspilot is an extension of the differentialpilot class.
I think this is a limit of the nxt g interface not the sensor itself.
The nxt compass sensor contains a digital magnetic compass that measures the earth s magnetic field and calculates a heading angle.
The essentials are things every nxt programmer should know.

Since the us sensor block returns only a single byte the sensor returns the heading angle divided by two currently.
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.
Programming the nxt compass sensor to point in the right direction.
The current heading is calculated to the nearest 1 and refreshed 100 times per second.
To use the compass sensor from nxt g an additional piece of software needs to have been added to your computer.
It needs a hitechnic or mindsensors compass sensor plugged in to one of the sensor ports.
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.
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 nxt sensor ports support three different types of sensor.
Using the hitechnic compass sensor with nxt g.
But if you are using a port splitter or a remote nxt or rcx it may be of interest.
The current heading is calculated to the nearest 1 and refreshed 100 times per second.
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.
