This is the fixup which works at the low end of the knob, and also provides limits at 0 and 99. Since I've got this to work, maybe I won't use Paddle2See's really great knob control on the knob calculator project he mentioned. This is a simpiification of my previous mini-project showing how to spin a knob control, and showing two seven segment displays for the number. Maybe you will find something like this useful for your projects? Maybe you will have some improvements on this project? Have fun scratching!
