  Project name:
     Arduino 1-Wire Thermocouple in the kitchen- 13 # arduSerie
     Flavour I

      Description:
      This serie makes several experiments with thermocouple in the home kitchen.
      The purpose is to record the temperature over time. We will experiment with 
      cheese bread, sandwich cheese, gelatin and more. Here we will make the 
      thermocouple works without any components. Get on!!! Check it over !!!

  This is an example for the Adafruit Thermocouple Sensor w/MAX31855K
  Designed specifically to work with the Adafruit Thermocouple Sensor
  ----> https://www.adafruit.com/products/269
  These displays use SPI to communicate, 3 pins are required to
  interface
