Re: Analog read of off-the-shelf potentiometer
The analog ports have 0V, 5V, and the input.http://content.vexrobotics.com/docs/VEXnet_Cortex_UserGuide_081811.pdf
One side of the pot goes to 0V, the other goes to 5V, and the wiper goes to the analog input.
The pot should be 5K Ohm.
You should measure from 0V to 5V on the analog input with a DMM as you turn the pot.
Please provide a schematic and pot data if it still does not work.
