The compass sensor connects to an nxt sensor port using a standard nxt wire and uses the digital i2c communications protocol.
Nxt compass sensor tutorial.
It s important to do these exercises not just assume you get it the advanced section is for reference purposes.
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.
Programming the nxt compass sensor to point in the right direction.
The essentials are things every nxt programmer should know.
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.
Using hitech compass sensor.
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.
This is a guide to using the motors and sensors from the lego nxt set with a parallax basic stamp ii or bs2.
Using nxt components with a micro controller.

The current heading is calculated to the nearest 1 and refreshed 100 times per second.
This tutorial for lego mindstorms nxt is divided in two sections.
The compass sensor is housed in a standard mindstorms sensor housing to match the other mindstorms elements.
It needs a hitechnic or mindsensors compass sensor plugged in to one of the sensor ports.
Since the us sensor block returns only a single byte the sensor returns the heading angle divided by two currently.
I think this is a limit of the nxt g interface not the sensor itself.
Some of these movies have exercises directly under them.
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.
The nxt sensor ports support three different types of sensor.
Program using labview lego.
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.
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.
