/* Analog input, serial output Reads an analog input pin, prints the results to the serial monitor. The circuit: * Potentiometer connected to analog pin 15. * Center pin of the potentiometer goes to the analog pin. * Side pins of the potentiometer go to +3.3V (VCC) and ground created over and over again by Tom Igoe and everyone who's ever used Arduino Ported to Maple 27 May, 2010 by Bryan Newbold */ // Analog input pin.
