Compass Compatibility With ARC

Hi , I have been shopping for sensors and reading about 2d mapping using.radar.extra.and I also read on some random sites that a good electronic compass is a good addition to get your robot correct orientation if it deviated from a original path avoiding a object or if the little guy.just.just drive perfectly straight. are these compass modules useful.to.tell your.robot which.direction to.go.or slightly correct.itself? I apologize for all the random periods because I just bought a new Samsung galaxy note and IM still getting use to it. The auto correct is changing words to what it thinks I should have said I guess lol

I like the LEDs around the edge showing the direction. Its hard to say if its straightforward to intergrate to the EZB it doesn't say anywhere that I can find that its I2C probably isn't.

The Sure Electronics DC-SS503V100 already added by DJ to EZB is a better bet but difficult to obtain now as it looks like discontinued stock (in the UK in any case)

The device I like is SparkFun Compass Module - HMC6352 Product Code: SEN-07915 which has I2C and all the documentation perhaps someone on here has already added it to EZB or has another opinion

Found this Arduino code for it. (Might point us in the right direction) ;-)

Looks like it is serial, so it should work with the EZ-B if configured correctly.

#include 
#include 
void setup()
{
    Serial.begin(9600);
}
void loop()
{
     int i;
     compass c;
    i=c.data(2,3);
    Serial.println(i);
    delay(100);
}

budel0 go! I was not able to find it on ebay and here it is! I'm also waiting to see if it works well, I guess that somehow affect the magnetic fields of the speakers if they are located near the sensor. I have also read in the tutorial DJ i2c connection cables must be short.

So I must use code there's no ARC option for a I've compass?
