MKR1000 and DS18B20 temperature sensor I am new to Arduino and electronics in general and I can't get my MKR1000 to read correct data from a DS18B20 temperature sensor.

Here is the tutorial I followed.

The issue is: I always get the same readings from the sensor: -127.00. 

I should mention I have tried 2 different sensors and get the same readings.

From the sensor, GND goes directly to GND on the board, and I have the 4.7kΩ resistor in between the data and power wires.

According to the sensor manufacturer, output leads: Yellow (VCC), Red (DATA), Black (GND).

Data line is connected to the pin ~2 on the MKR1000.

/********************************************************************/
// First we include the libraries
#include &lt;OneWire.h&gt; 
#include &lt;DallasTemperature.h&gt;
/********************************************************************/
// Data wire is plugged into pin 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(&amp;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 temperature readings 
 Serial.println("DONE"); 
/********************************************************************/
 Serial.print("Temperature is: "); 
 Serial.print(sensors.getTempCByIndex(0)); // Why "byIndex"?  
   // You can have more than one DS18B20 on the same bus.  
   // 0 refers to the first IC on the wire 
   delay(1000); 
}


Any idea what I am doing wrong?
Looks like you have it wired wrong.  A schematic would really help but it looks like you've got 5V going directly into the sensors data line (yellow wire) it's connected on your breadboard to the orange wire +5V.  The power wire of your temperature sensor (red wire) is running through a 4.7K resistor which is not likely what you wanted here either.
