thank you for your time & efforts but unfortunately those links were just too meaningless for my understanding/comprehension level, its just to symbolic and or vague, maybe something english will suffice? or even better in C++ / Arduino programming language will be best, i have gone thru many youtube videos dozens and just not clicking in again either they speak to vague or the application example is non related to my application, im dealing with a dc motor and a potentiometer for feedback close loop and what i need is the PD Controller and often you everything is about PID or PI
