/*

  Analog input, analog output, serial output

  Reads an analog input pin, maps the result to a range from 0 to 255 and uses

  the result to set the pulse width modulation (PWM) of an output pin.

  Also prints the results to the Serial Monitor.

  The circuit:

  - potentiometer connected to analog pin 0.

    Center pin of the potentiometer goes to the analog pin.

    side pins of the potentiometer go to +5V and ground

  - LED connected from digital pin 9 to ground
