The 6xAA battery pack works great. I have two motors rotating (arm linkages of an OWI edge arm) successfully from the gyro data thru the mega into a toshiba dual motor driver driving the dc motors.
Then I integrated the z rotation angle to compute the absolute angle. The idea is that the gyroscope produces a delta angle (call it θ):
θ = ∫0t θt dt
the gyro is giving readings in degrees/second. What time interval is being used to make
the data? Is there a constant clock (SCL?) time value? If I turn the gyro 10 degrees in one second
it gives a reading of 10. If I turn the gyro 10 degrees in 1 ms it gives a reading of 10,000. How do I determine the time of the rotation to integrate?
I believe our project requirements permit using the gyro (sensors) breakout boards. However,
we have to make our own power supply boards, motor driver boards, and microcontroller (eagle and send to pcb printer) boards.
2. Do you sell the individual driver chips like DRV8833 (need to drive 6 motors) or only the breakout boards? Any surface mount soldering suggestions? Do you sell individual chips like atmels or power regulators?
