SendATweet
Demonstrates sending a tweet via a Twitter account using the Temboo Arduino Yun SDK.
Check out the latest Arduino & Temboo examples and support docs at http://www.temboo.com/arduino
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. Note that since this
sketch creates a new tweet, your application will need to be configured with
read+write permissions. 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.
Looking for social APIs? We've got Facebook, Google+, Instagram, Tumblr and more.
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'll need to edit the placeholder version of TembooAccount.h included with this example sketch,
by inserting your own Temboo account name and app key information. The contents of the file should
look like:
#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
You can find your Temboo App Key information on the Temboo website,
under My Account > Application Keys
The same TembooAccount.h file settings can be used for all Temboo SDK sketches.
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.
