For example, I have a 10k ohm (linear) Thumbwheel Potentiometer. This POT will produce values from 0 to 10k when reading its resistance.
How do I shift resistance range values by X ohms in the positive direction? E.g. a 10k POT will yield a new range of: 10 to 10,010 ohm, shifted by 10 ohms?
Since I am using an Arduino, I could programmatically scale the resistance value. But I do not want to do that.
- How do I shift resistance value range by X ohms in the negative direction? E.g. a 10k POT will yield a new range of: -10 to 9990 ohm, shifted by 10 ohms?
