Guide to gyro and accelerometer with Arduino including Kalman filtering

Hi Lauszus,

Like the many others, I got my IMU working by studying at lot of your hard work, just wanted you to know that I really appreciate it!
I have a question, with the project I'm working on - I need to filter out the accel data that is affecting the
Kalman output such as when the IMU is under accel in any of the 3 axis. For example while placing the IMU
on a rotating platform, the addition of of the X or Y accel vectors start to affect the roll
and pitch angles. What do you recommend to eliminate these bias errors for when the IMU is not stationary and under accel/decel?
