 1. Check and correct your pin out -> Refer to the pictures in the [Electronics](#electronics) section below.
 2. Tune dead zone to avoid jittering
 3. Getting min and max values for your joysticks
 	- There is a semi-automatic approach, which returns you the minimum and maximum values seen within 15s.

+Choose a modifier function with the help of the following picture. Note, that the Squared, Squared Tan and Cubed Tan function act like a deadzone filter, because small inputs are resulting in nearly zero output, which may reduced unwanted movements. 
+Also note, that some of those functions are already at their maximum output (and therefore limited), before the input reaches 350.
