DESCRIPTION
This potentiometer module is able to slide forward and backward. The output range is from 0 - VCC depending on the varying resistance based on the slider.
"A potentiometer is an instrument for measuring the potential (voltage) in a circuit. A fraction of a known voltage from a resistive slide wire is compared with an unknown voltage by means of a galvanometer. The sliding contact or wiper of the potentiometer is adjusted and the galvanometer briefly connected between the sliding contact and the unknown voltage. The deflection of the galvanometer is observed and the sliding tap adjusted until the galvanometer no longer deflects from zero. At that point the galvanometer draws no current from the unknown source, and the magnitude of voltage can be calculated from the position of the sliding contact."
