PIDs out of control

[wildaburk3160]

From what we've gathered, the PotentiometerGetNormalized.vi gets the voltage reading from the potentiometer and returns it as some sort of proportion of the total possible voltage. It seems that 90 degrees ~ .1 change in the returned value.

So, if we were to set our "midpoint" at the middle of the pots rotational range, we would set our setpoint to .50. Our goal then is to rotate at maximum 90 degrees in either direction from this point. Theoretically, this should change the value by .1, but it has a small variation, so we have it set to where we manually control the "maximum" and "minimum" values of the pot.

None of these values we have set come up near the extreme values of rotation, which would either be "0" or "1".

We haven't thrown in any limitations to rotations in the program other than how far we can change the setpoint, but I will soon implement something.
