Guide to gyro and accelerometer with Arduino including Kalman filtering

Hey Lauszus!

I was hoping to learn something about using IMU effectively with the help of Kalman filtering as I came across this wonderful tutorial. The only problem I have is I have 2 separate gyro and accelerometer modules (L3G4200D and ADXL 335). How do I combine and use them according to your pin config.

gyro has pins GND, VIN, SCL, SDA, SDD, INT1, INT2 and accelerometer pins are VCC, GND,X,Y,Z,ST. Where do these pins go?

Thanks!
