Assume I have a linear potentiometer that, say, has a range of 0 to 10Kohm. Then assume that:
0deg = 0 ohms
10deg = 370 ohms
270deg = 10Kohm
My question is, how do I show 370 ohms while the potentiometer is ≤ 10 degrees, but as soon as it gets > 10 degrees, ONLY the potentiometer value is shown (e.g. 11deg would show about 407 ohms)? That is, IGNORE the potentiometer when it is ≤ 10 degrees, but then continue as normal past 10 degrees.
I could do it with an active design, but was wondering if there was a way to do it with just passive components that for some reason I'm not seeing..
Note that the reason this has to be done with external components (rather than just change the potentiometer range to be 370-10K) is that the additional floor needs to be switchable.
