      Project: Weather Reporter: Temboo, Ethernet, Arduino
        Title: ARDUINO MASTER: Get temperature from Yahoo using Temboo
  Arduino IDE: 1.6.0
       Description: The following sketch was designed for the Arduino MASTER device. 
               It will retrieve temperature/weather information from Yahoo using your
               Temboo account (https://www.temboo.com/), which will then be sent to the
               Arduino Slave device to be displayed on a TFT LCD module.
               
   Libraries : Ethernet Library (that comes with Arduino IDE)
               Temboo Arduino Library - https://www.temboo.com/sdk/arduino
               
   Temboo Library installation instructions for Arduino: 
               https://www.temboo.com/arduino/others/library-installation

  You will also need to copy your Temboo Account information into a new tab and call it TembooAccount.h.
