Hey, i still didn't solve it 
I'll explain why the setup for and what is my problem.
As you see i have a WiFi shield connected, i send him commands to spin the servo that is connected to a arm that the gyro is on so the gyro spins with it.
I want to tell the servo to spin 90 degrees, and then go back to 0 degrees, and do that in a loop.
That's why i need the Gyro for, to get the degrees.
My problem is that after 2-3 time it goes to 90 then 0 the drifting goes crazy and it goes to 110 then -20...
So my problam still isn't solved.
I posted all my setup so you can see if i'm doing everything right, i hope you can help me figure it out.
