Hi. I would like to use a digital temperature sensor on Arduino Uno. I downloaded 2 files "Dallas Temperature and One wire" and added them to the Arduino library. Below is the code am using;
#include <OneWire.h>
#include <DallasTemperature.h>
// Data wire is plugged into port 2 on the Arduino
#define ONE_WIRE_BUS 2
// Setup a oneWire instance to communicate with any OneWire devices (not just Maxim/Dallas temperature ICs)
OneWire oneWire(ONE_WIRE_BUS);
//
// Pass our oneWire reference to Dallas Temperature.
DallasTemperature sensors(&oneWire);
void setup(void)
{
// start serial port
Serial.begin(9600);
Serial.println("Dallas Temperature IC Control Library Demo");
// Start up the library
sensors.begin();
}
void loop(void)
{
// call sensors.requestTemperatures() to issue a global temperature
// request to all devices on the bus
Serial.print("Requesting temperatures...");
sensors.requestTemperatures(); // Send the command to get temperatures
Serial.println("DONE");
Serial.print("Temperature for the device 1 (index 0) is: ");
Serial.println(sensors.getTempCByIndex(0));
}
When I run the code, I get the error message below;
C:\Program Files (x86)\Arduino\libraries\DallasTemperature\DallasTemperature.cpp:9:26: fatal error: WConstants.h: No such file or directory
#include "WConstants.h"
^
compilation terminated.
Error compiling.
Can someone help me resolve this.
Thanks.
