SendDataToGoogleSpreadsheet
|
|
|
|
Demonstrates appending a row of data to a Google spreadsheet
|
|
from the Arduino Yun 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
|
|
|
|
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
|
|
|
|
Since this sketch uses a Google spreadsheet, you'll also need a
|
|
Google account: substitute the placeholders below for your Google account values.
|
|
|
|
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).
|
|
|
|
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.
|
|
|
|
(Be sure to delete this comment after creating your TembooAccount.h file!)
