Hello Electro Tech Awesome
I am working with something prebuilt that uses a potentiometer as a voltage divider.
The voltage input is 3v and it should normally (middle positioned) have 1,5v.
This works fine, but I want to lower the gain of the output voltage. Lets say that I normally would have moved the potentiometer so it had an output of 1.7v but I rather want it to be 1.6v. Same goes for moving the potentiometer in the other direction, giving me 1.3v but I want 1.4v
I want it to be more precise, and I don't care that I lose some of my higher values.
But can it even be done in a simple way? I thought maybe a parallel voltage divider would work, it does abit, but it then differs the value from what side I go to from the middle position. Scaling from 1.1v - 1.5v and 1.5v - 2.4v
Can this be done in any way?
This is what I did so far I had an idea this would work, and I wont figure out why just now
The green circle is my newly added voltage divider.
