// No hay que usar la librería OneWire de Arduino, sino la que tengo en OneWireNoResistor-1.0

// Modifiqué el DS18x20_NoPullupTester_Juan para que simplemente tire datos de los sensores conectados en modo parásito.
// Los datos vienen separados por coma entre los sensores y, al terminar, finaliza la linea y espera X segundos.

// This is an updated version of the Tester program that comes with the DallasTemp library
// It will drive a DS18x20 tempurature sensor plugged directly to the Arduino header pins 8,9, and 10.
// The flat side of the sensor should face into the center of the board.
// More info and a video here...
