+ ReadATweet
+
+ Demonstrates retrieving the most recent Tweet from a user's home timeline
+ using the Temboo Arduino Yun SDK.
+
+ A Temboo account and application key are necessary to run all Temboo examples.
+ If you don't already have one, you can register for a free Temboo account at
+ http://www.temboo.com
+
+ In order to run this sketch, you'll need to register an application using
+ the Twitter dev console at https://dev.twitter.com. After creating the
+ app, you'll find OAuth credentials for that application under the "OAuth Tool" tab.
+ Substitute these values for the placeholders below.
+
+ This example assumes basic familiarity with Arduino sketches, and that your Yun
+ is connected to the Internet. For more tutorials on using the Temboo Library and
+ Temboo Arduino Yun SDK, visit http://www.temboo.com/arduino
+
+ This example code is in the public domain.

+ IMPORTANT NOTE: TembooAccount.h:
+
+ TembooAccount.h is a file referenced by this sketch that contains your Temboo account information.
+ You need to create this file. To do so, make a new tab in Arduino, call it TembooAccount.h, and
+ include the following variables and constants:
+
+ #define TEMBOO_ACCOUNT "myTembooAccountName" // your Temboo account name
+ #define TEMBOO_APP_KEY_NAME "myFirstApp" // your Temboo app key name
+ #define TEMBOO_APP_KEY "xxx-xxx-xxx-xx-xxx" // your Temboo app key
+
+ The same TembooAccount.h file settings can be used for all Temboo SDK sketches.
+
+ Visit https://www.temboo.com/account to access your Temboo account credentials.
+
+ Keeping your account information in a separate file means you can save it once,
+ then just distribute the main .ino file without worrying that you forgot to delete your credentials.
