[modifier] Principle analysis

Main component of the Me Potentiometer module is a resistor with three terminals and its resistance can be adjusted according to a kind of variation. The resistor usually comprises a resistor and a moving electric brush. Based on the voltage-dividing principle of series resistors, when the electric brush moves along the resistor body, a resistance value with certain relation to the displacement of electric brush is obtained at the output end, and consequently a different voltage is output from the analog port. This module can be used with other module to build some interesting projects, for example, used with DC motor to build a speed-controllable toy car, or used with LED to build a dimmable lamp.
