Krodal,

Got it working, in a sense.  i2c_scanner finds it and your code reports XYZ values.  Unfortunately, the values simply oscillate (except for Z, which is stuck at zero).  I rapidly rotate the board back and forth 180 degrees but the oscillation remains constant.  Restarting the sketch gives me new pairs of numbers, but they're stuck, too.  Am I simply unable to spin the board fast enough to change the values?  Or did I break it?

Thanks.

Krodal,

This is very helpful.  I particularly appreciate knowing about i2c_scanner...it'll let me know whether I fried the board when I soldered the header to it.

And I did notice the alternate reality.  Quite a coincidence.

Thank you very much.

Krodal,

Thanks very much for the link.  I'd actually already found it and downloaded the source and got it to compile.  I did not, however, find a circuit.  I did find this: http://arduino.cc/playground/uploads/Main/MPU6050-V1-SCH.jpg.  Maybe I'm an idiot, but I struggle to map it to the GY-521.  How about a GY-521-specific circuit diagram that shows connections between the 521 and an Arduino?  Surely such a thing must exist?

Many thanks.

Greetings.  I'm trying to put together a simple Arduino project with the gy-521 but I can't, here or anywhere else, find a sample circuit...and I'm too much of a noob to design one myself.  Can anyone point me in the right direction?

Many thanks.
