/*
ReadAnalogVoltage
Reads an analog input on pin 0, converts it to voltage, and prints the
result to the Serial Monitor also on LCD.
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.
