/* Multiple DS18B20 1-Wire digital temperature sensors with Arduino example code. More info: https://www.makerguides.com */

// Include the required Arduino libraries:
#include "OneWire.h"
#include "DallasTemperature.h"


// Define to which pin of the Arduino the 1-Wire bus is connected:
#define ONE_WIRE_BUS 2

// Create a new instance of the oneWire class to communicate with any OneWire device:
OneWire oneWire(ONE_WIRE_BUS);

// Pass the oneWire reference to DallasTemperature library:
DallasTemperature sensors(&oneWire);
