/*
AnalogReadSerial
Reads an analog input on pin 0, prints the result to
the serial monitor.
Graphical representation is available using serial
plotter (Tools > Serial Plotter menu)
Attach the center pin of a potentiometer to pin A0, and
the outside pins to +5V and ground.

This example code is in the public domain.
