Adjustable signal voltage control with 2.5v center
I need help finding a kit or parts to solve what I thought would be a simple problem.
I have a motor controller that has the ability to have analog input devices like a potentiometer or an analog joystick. The input signals are 0v-5v DC with a 2.5v center point. When the analog device is calibrated correctly it is easy to achieve the 0v-5v DC.
But what if you want to add gain to the input signal and maintain the 2.5v center or add loss to the input signal and maintain the 2.5v center. Or what if you replace the analog device with a hall effect sensor that has voltages that are not quite 0v-5v DC? Another example is to have limitation adjustability so the center is always 2.5v but the min and max can be changed to something like 1.5v-3.5v with the same 2.5v center
Thanks for any help or suggestions.
