| 3 | + |
| 4 | + Demonstrates making a request to the Yahoo! Weather API using the Temboo Arduino Yun SDK. |
| 5 | +
|
| 6 | + Check out the latest Arduino & Temboo examples and support docs at http://www.temboo.com/arduino |
| 7 | + |
| 8 | + A Temboo account and application key are necessary to run all Temboo examples. |
| 9 | + If you don't already have one, you can register for a free Temboo account at |
| 10 | + http://www.temboo.com |
| 11 | + |
| 12 | + This example assumes basic familiarity with Arduino sketches, and that your Yun is connected |
| 13 | + to the Internet. |
| 14 | +
|
| 15 | + Looking for another API? We've got over 100 in our Library! |
| 16 | + |
| 17 | + This example code is in the public domain. |

| 97 | + IMPORTANT NOTE: TembooAccount.h: |
| 98 | +
|
| 99 | + TembooAccount.h is a file referenced by this sketch that contains your Temboo account information. |
| 100 | + You'll need to edit the placeholder version of TembooAccount.h included with this example sketch, |
| 101 | + by inserting your own Temboo account name and app key information. The contents of the file should |
| 102 | + look like: |
| 103 | +
|
| 104 | + #define TEMBOO_ACCOUNT "myTembooAccountName" // your Temboo account name |
| 105 | + #define TEMBOO_APP_KEY_NAME "myFirstApp" // your Temboo app key name |
| 106 | + #define TEMBOO_APP_KEY "xxx-xxx-xxx-xx-xxx" // your Temboo app key |
| 107 | +
|
| 108 | + You can find your Temboo App Key information on the Temboo website, |
| 109 | + under My Account > Application Keys |
| 110 | +
|
| 111 | + The same TembooAccount.h file settings can be used for all Temboo SDK sketches. |
| 112 | +
|
| 113 | + Keeping your account information in a separate file means you can save it once, |
| 114 | + then just distribute the main .ino file without worrying that you forgot to delete your credentials. |
