|
---|
| 3 |
|
---|
| 4 | Demonstrates making a request to the Envirofacts API using Temboo from an Arduino Y炭n.
|
---|
| 5 | This example retrieves the names and addresses of EPA-regulated facilities in the
|
---|
| 6 | Toxins Release Inventory (TRI) database within a given zip code.
|

| 8 | Check out the latest Arduino & Temboo examples and support docs at http://www.temboo.com/arduino
|
---|
| 9 |
|
---|
| 10 | A Temboo account and application key are necessary to run all Temboo examples.
|
---|
| 11 | If you don't already have one, you can register for a free Temboo account at
|
---|
| 12 | http://www.temboo.com
|
---|
| 13 |
|
---|
| 14 | This example assumes basic familiarity with Arduino sketches, and that your Y炭n is connected
|
---|
| 15 | to the Internet.
|
---|

| 154 |
|

| 155 | TembooAccount.h is a file referenced by this sketch that contains your Temboo account information.
|
---|
| 156 | You'll need to edit the placeholder version of TembooAccount.h included with this example sketch,
|
---|
| 157 | by inserting your own Temboo account name and app key information. The contents of the file should
|
---|
| 158 | look like:
|
---|
| 159 |
|
---|
| 160 | #define TEMBOO_ACCOUNT "myTembooAccountName" // your Temboo account name
|
---|
| 161 | #define TEMBOO_APP_KEY_NAME "myFirstApp" // your Temboo app key name
|

| 162 | #define TEMBOO_APP_KEY "xxx-xxx-xxx-xx-xxx" // your Temboo app key
|
---|
| 163 |
|
---|
| 164 | You can find your Temboo App Key information on the Temboo website,
|
---|
| 165 | under My Account > Application Keys
|
---|
| 166 |
|
---|
| 167 | The same TembooAccount.h file settings can be used for all Temboo SDK sketches.
|
---|
| 168 |
|

| 169 | Keeping your account information in a separate file means you can share the main .ino file without worrying
|
---|
| 170 | that you forgot to delete your credentials.
