I need to provide a 2v input voltage to a POT. I thought about the attached diagram but realized that, as the pot changes it resistance, that the input voltage would also change. I need a steady voltage to measure the POT setting with the ADC. FYI: The POT is on a linear actuator and my ADC has a built-in reference voltage of 2v so anything higher flat lines. Any help would be much appreciated!
