|

3 |
|
---|
4 | Demonstrates retrieving the most recent Tweet from a user's home timeline
|
---|
5 | using Temboo from an Arduino Y炭n.
|
---|
6 |
|
---|
7 | Check out the latest Arduino & Temboo examples and support docs at http://www.temboo.com/arduino
|
---|
8 |
|
---|
9 | A Temboo account and application key are necessary to run all Temboo examples.
|
---|
10 | If you don't already have one, you can register for a free Temboo account at
|
---|
11 | http://www.temboo.com
|
---|
12 |
|
---|
13 | In order to run this sketch, you'll need to register an application using
|
---|
14 | the Twitter dev console at https://dev.twitter.com. After creating the
|
---|
15 | app, you'll find OAuth credentials for that application under the "OAuth Tool" tab.
|
---|
16 | Substitute these values for the placeholders below.
|
---|
17 |
|
---|
18 | This example assumes basic familiarity with Arduino sketches, and that your Y炭n
|
---|
19 | is connected to the Internet.
|
---|
20 |
|
---|
21 | Want to use another social API with your Arduino Y炭n? We've got Facebook,
|
---|
22 | Google+, Instagram, Tumblr and more in our Library!

155 | IMPORTANT NOTE: TembooAccount.h:
|
---|
156 |
|
---|
157 | TembooAccount.h is a file referenced by this sketch that contains your Temboo account information.
|
---|
158 | You'll need to edit the placeholder version of TembooAccount.h included with this example sketch,
|
---|
159 | by inserting your own Temboo account name and app key information. The contents of the file should
|
---|
160 | look like:
|
---|
161 |
|
---|
162 | #define TEMBOO_ACCOUNT "myTembooAccountName" // your Temboo account name
|
---|
163 | #define TEMBOO_APP_KEY_NAME "myFirstApp" // your Temboo app key name
|
---|
164 | #define TEMBOO_APP_KEY "xxx-xxx-xxx-xx-xxx" // your Temboo app key
|
---|
165 |
|
---|
166 | You can find your Temboo App Key information on the Temboo website,
|
---|
167 | under My Account > Application Keys
|
---|
168 |
|
---|
169 | The same TembooAccount.h file settings can be used for all Temboo SDK sketches.
|
---|
170 |
|
---|
171 | Keeping your account information in a separate file means you can share the main .ino file without worrying
|
---|
172 | that you forgot to delete your credentials.
