A potentiometer controls the amount of resistance of a circuit. The higher the resistance setting, the lower the analog reading of that input (or maybe otherway around). Teams use this to figure out the angle that the potentiometer is turned to. For example if a rotatable device is connected to the potentiometer, as the device rotates the resistance and the input value would change.
