    Math Question

    I have a unique problem I need to solve via math. As I turn a potentiometer it's output goes from 179 to 0, what I need is a math formula that changes that to a 181 to 360 Is that even possible??

    Thanks
    Rob

    Hi Rob
    not sure which way round you want it but

    converted value=(1-potvalue)+360
    so at
    pot 0 1-0+360= converted value of 360
    pot 179 1-179+360=converted value of +182

    or the other way round is
    converted value = 360-potvalue
    so
    pot at 179 360-179 =converted value of+181
    pot at 360 360-1 = converted value of 360

    I use 1, don't use 0 as computers crash if you try to subtract from 0

    hope this is what you wanted
    kind regards
    geoff

    Thanks, I figured it out just before bed last night. Take the input times -1 then add 360 That is a programmable formula with no need for tables.
