 /*
   * Ideas/TODO:
   * POT_MIN, POT_MAX as variable with calibration procedure. Drive slowly to both ends until value does not get lower.
-  * Motor error checking. Timeout overall (if regulation fails or stuck). Timeout movement (motor is tunring but no change in poti value detected). Move right direction.
-  * Hardware: motorentstörkondensatoren einbauen direkt an motor. 47nF + zu - und zwei 10nF + zu case und - zu case
-  * PI Optimieren. aktuell overshoot
-  * Implement knob menu structure
