I2C LCD causes problems

I just couldn't wait until tomorrow to try the code. Sitting in chair tonight thinking about the code it came more clear so I just HAD to come out and see if I could get it working..... IT WORKED!!!!

Yep, as I turn pot there is the bump as LCD updates, then stop turning pot and everything evens out and motor runs smoothly.

WOW!! I'm impressed with ya'll the way ya'll have been able to talk me thru this code, and write code for me to use.

Thank ya'll so VERY MUCH!
