I would like to have a Rotary knob that would select between eight
specific voltages (to come out of the rotary to a jack). The voltages
would *not* have to be exact, maybe like within 0.5 volts (+ or -) of
the intended voltage.
Could I do this by supplying +10v to eight different resistors, and
connecting the other end of each resistor to the eight inputs of the
rotary knob? (and then the output of the rotary to a jack) Assuming
I get the right resistor for each specific voltage I want, would this
work?
I suppose I could use resistor trimmers or even potentiometers instead
of resistors for a more adjustable setup?
thanks :)
