|
---|
| 4 | Demonstrates uploading a file to a Dropbox account using Temboo from an Arduino Y炭n.
|
---|
| 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 | You'll also need a valid Dropbox app and accompanying OAuth credentials.
|
---|
| 13 | To create a Dropbox app, visit https://www.dropbox.com/developers/apps and
|
---|
| 14 | do the following:
|
---|
| 15 |
|
---|
| 16 | 1. Create a "Dropbox API app"
|
---|
| 17 | 2. Select "Files and datastores"
|
---|
| 18 | 3. Select "Yes - my app only needs access to the files it creates."
|
---|
| 19 |
|
---|
| 20 | Once you've created your app, follow the instructions at
|
---|
| 21 | https://www.temboo.com/library/Library/Dropbox/OAuth/ to run the Initialize and Finalize
|
---|
| 22 | OAuth Choreos. These Choreos complete the OAuth handshake and retrieve your Dropbox OAuth access tokens.
|
---|
| 23 |
|
---|
| 24 | This example assumes basic familiarity with Arduino sketches, and that your Y炭n is connected
|
---|
| 25 | to the Internet.
|
---|
| 26 |
|
---|
| 27 | Looking for another API to use with your Arduino Y炭n? We've got over 100 in our Library!
|
---|
| 28 |
|
---|
| 29 | This example code is in the public domain.
