Always wear safety glasses while programming.
Thanks for help guys!
This laste if and is important, because of tolerance on POT and so, is better to ahve some more dead time between forward and reverse! Will try this and let you know how it works.
I'd considered a 'dead window' in the middle, but didn't go there as you'd not asked & thought it better to keep it 'pure' so to speak - not sure how/the tolerance of the pot comes into play with respect to you last post - the tolerance refers to how far out the actual resistance is from the specified resistance - you don't really care whether say a 10k pot is 9.8k or 10.2k ...the middle point of your pot will be 127 (unless they've some whacky non linear way of making the pot's carbon track!)...you need the 'dead window' not for tolerance purposes, but to have a better chance of finding/hitting the point on the pot where both sides are at rest.
