  SendAnEmail

  Demonstrates sending an email via a Google Gmail account using Temboo from an Arduino Y炭n.

  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

  Since this sketch uses Gmail to send the email, you'll also need a valid 
  Google Gmail account. The sketch needs the username and password you use 
  to log into your Gmail account - substitute the placeholders below for these values.

  This example assumes basic familiarity with Arduino sketches, and that your Y炭n is connected
  to the Internet.
  
  Looking for another API to use with your Arduino Y炭n? We've got over 100 in our Library!

  This example code is in the public domain.

/*** SUBSTITUTE YOUR VALUES BELOW: ***/

// Note that for additional security and reusability, you could
// use #define statements to specify these values in a .h file.

// your Gmail username, formatted as a complete email address, eg "bob.smith@gmail.com"

// your Gmail password
const String GMAIL_PASSWORD = "xxxxxxxxxx";

/*
  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 share the main .ino file without worrying 
  that you forgot to delete your credentials.
