+  Reads an analog input on pin 0, converts it to voltage, and 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.
