- UploadToDropbox
-
- Demonstrates uploading a file to a Dropbox account using Temboo from an Arduino Yun.
-
- Check out the latest Arduino & Temboo examples and support docs at http://www.temboo.com/arduino
-
- 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
-
- You'll also need a valid Dropbox app and accompanying OAuth credentials.
- To create a Dropbox app, visit https://www.dropbox.com/developers/apps and
- do the following:
-
- 1. Create a "Dropbox API app"
- 2. Select "Files and datastores"
- 3. Select "Yes - my app only needs access to the files it creates."
-
- Once you've created your app, follow the instructions at
- https://www.temboo.com/library/Library/Dropbox/OAuth/ to run the Initialize and Finalize
- OAuth Choreos. These Choreos complete the OAuth handshake and retrieve your Dropbox OAuth access tokens.
-
- This example assumes basic familiarity with Arduino sketches, and that your Yun is connected
- to the Internet.
-
- Looking for another API to use with your Arduino Yun? We've got over 100 in our Library!
-
- 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'll need to edit the placeholder version of TembooAccount.h included with this example sketch,
- by inserting your own Temboo account name and app key information. The contents of the file should
- look like:
-
- #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
-
- You can find your Temboo App Key information on the Temboo website,
- under My Account > Application Keys
-
- The same TembooAccount.h file settings can be used for all Temboo SDK sketches.
-
- Keeping your account information in a separate file means you can share the main .ino file without worrying
- that you forgot to delete your credentials.
