The AdafruitTwitter class requires WICED Feather Lib 0.5.5 or higher to run.

The AdafruitTwitter class makes sending tweets easy via a custom Application that you can setup using this learning guide.

1. Creating a WICED Twitter Application

In order to enable WICED to interact with Twitter, you first need to log in to twitter's app admin console at http://apps.twitter.com and create a new app:

Enter the Application Details

Next you need to enter your application details, based on the following data:

The NAME field must be globally unique, so you should make it something personal like adding your twitter username.

Then accept the license terms and click the Create your Twitter application button at the bottom of the page.

This will redirect you to the main app config page, as shown below:
