Note from MakeKit

This is an attempt to create an auto-correction of the Yaw-movement on the Air:bit drone. The compass heading is compared to a desired compass heading, then the difference is being multiplied with a proportional (PID) number and set to Yaw.

• Challenge: The compass heading block uses the accelerometer in it´s equation. The accellerometer will give erradical numbers when motors are spinning. Therefore, these numbers needs to be smoothed with a low pass filter.

The low pass filter and the compassCorrectionFactor needs to be adjusted.

As time of writing (August 2020), the algorithm is not working
