+ SendDataToGoogleSpreadsheet
+
+ Demonstrates appending a row of data to a Google spreadsheet from the Arduino Yun
+ 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
+
+ Since this sketch uses a Google spreadsheet, you'll also need a
+ Google account: substitute the placeholders below for your Google account values.
+
+ This example assumes basic familiarity with Arduino sketches, and that your
+ Yun is connected to the Internet.
+
+ The columns in your spreadsheet must have labels for the Choreo to
+ work properly. It doesn't matter what the column labels actually are,
+ but there must be text in the first row of each column. This example
+ assumes there are two columns. The first column is the time (in milliseconds)
+ that the row was appended, and the second column is a sensor value
+ (simulated in this example via a random number). In other words, your spreadsheet
+ should look like:
+
+ Time | Sensor Value |
+ ------+-----------------
+ | |
+
+ NOTE that the first time you run this sketch, you may receive a warning from
+ Google, prompting you to authorize access from a 3rd party system.
+
+ Looking for another API? We've got over 100 in our Library!
+
+ 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.
+
+ You can find your Temboo App Key information on the Temboo website,
+ under My Account > Application Keys
+
+ 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.
