Potentiometer Module is a part of Blockduino Kit. It was design to simplify the wiring connection between microntroller and the module. It have three wire connection which is Signal (S), Vcc (V) and Ground (G). The signal pin should be connected to Arduino analog pin (A0-A7), Vcc to +5v / +3.3v (ESP) and Ground. This Potentiometer Module use resistor 10K, the signal will send (0-5v) to Arduino pin.
