with a soft pot the result is similar to a slide potentiometer, except the fact the position isn't held. I was wondering if in the code, I could have the last position of my finger be recorded even if I remove my finger.
Here is a link to the code for the basics of the soft pots and some code
What does it read when not touched? ie, can you tell when it's not being touched? If so, easy, just retain the value when you detect that it's not touched, until it's touched again...
We need to know what value it gives when not touched, I assume this resting value will be the same whenever its not touched.
If thats the case should be relatively simple to code for.
Can you test this? Just paste the exact same code that is in that example link you posted and see what the values are when you touch highest point, lowest point and not at all.
