Hmc5883l Triple Axis Magnetometer Help

Hi So finally I got may HMC5883L Triple Axis Magnetometer through. But I can't seem to get it working and there doesn't seem to be any reference to it only a dual axis one. All connections were obvious so I know they are right. It's connected to the 3.3v not 5v. I can't say much more than that. I tried using the dual axis options but it only...

Accelerometer And Gyro Confusion

I think I may have got my self a little confused. What's the difference between an accelerometer and a gyro? Does an accelerometer return the movement of each angle or the angle itself?
question

Audio Transfer

Can audio be passed to and from the EZ-B? I need a mic mounted directly onto the robot as well as a speaker but with no wires between the robot and pc. I've found wireless mics and speakers to either be really low quality and/or too expensive. hat being said, I am thinking of using SmartVR with the EZ-B. Has anyone had any experience with this at...

question

I2c Query

Hi folks, I have another I2C query. I've learned now that I2C devices have addresses meaning multiple devices can be attached. This is awesome of course. My question is now, if I had, say 2 accelerometer's of the same type attached, can these be accessed separately? Am I correct in thinking that they would have the same address code? For scripting...
question

Expanding Digitalports

I was wondering if anyone had a simple solution for adding more digital connections to the controller. One idea I had was to link an arduino to it via i2c, although I don't know where to start to do that. I need to increase the connections by about 6 ( making 26 ) minimum.

question

3D Position

Hi This is difficult to ask. im in need of some kind of beacon to return a 3d position of the robot in relation to a fixed point. infrared not ideal unless it can move around objects/through walls etc beyond this im not sure how else to explain. I once saw something to do with VR about it but can't remember where.

A Question Of Torque

I was wondering if someone could give me a little clarity here. If using gears to reduce a servo's / motor's rotation by 50%, will that increase it's torque per cm? I'm going to be using a 40kg Servo and I am going to reduce its rotation from 210 degrees to 105.
question

Is It Falling?

I've just ordered a MMA7455 Accelerometer from good old ebay. This is going to sound a little daft but i'm going to need a little guidance. I''m going to be using it so I know what angle my bot is at but how can I use it to tell if the robot has been pushed or is falling? any advise on the subject would be greatly appreciated and I can't really say...
