Math Question

[737NUT]

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

Output = 360 - Input

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

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.
