Add these two libraries to "My Documents>Arduino folder>libraries folder 1.Arduino-Temperature-Control-Library-master.zip Link Address: https://github.com/milesburton/Arduino-Temperature-Control-Library Change the folder name From: "Arduino-Temperature-Control-Library-master "folder To: "Dallas Temperature" folder 2.OneWire.zip (for the latest OneWire library of arduino) Link Address: http://playground.arduino.cc/Learning/OneWire - you may backup first the old one from the arduino libraries.. Then place this new one and use the sample code below. Open the sample code: DS18x20_Temperature.ino/pde // OneWire DS18S20, DS18B20, DS1822 Temperature Example // // http://www.pjrc.com/teensy/td_libs_OneWire.html // // The DallasTemperature library can do all this work for you! // http://milesburton.com/Dallas_Temperature_Control_Library Wiring Connections: DS18B20 Temperature sensor - Gizduino RED wire ------------------> +5V ----> 4.7K ohms ----> BLUE wire BLACK wire ---------------> Ground
