/*
  AnalogReadSerial on ne UART placed on pins 0 and 1
  Reads an analog input on pin A0, 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 +3.3V and ground.
  Short together pin 0 and pin 1 with a wire jumper
