Remember that a body at constant velocity is not accelerating, so you can't tell if your device is stationary or moving at 100 kmh-1; you can only detect changes of velocity.

What about if it's changing direction but maintaining velocity?  :)

That isn't possible.
Velocity is a vector; a direction and a rate of displacement.
If you change either, the velocity has changed.

Sorry, you're absolutely right. I was thinking about a constant speed and a changing direction which is a change in acceleration. Carry on! :)

How can I use the received values to determine the angle at which the accelerometer is at any moment?
