Twittrix is a client implementation for the arduino server software at ngrash/max7219-ticker. It downloads original tweets that contain the hashtag "#34c3" and sends them to a connected arduino running the ticker software.
Make sure to set both TWITTER_CONSUMER_KEY and TWITTER_CONSUMER_SECRET.
These can be retrieved from your twitter app.
In addition, you can configure a different hashtag in config.exs.
Then run mix and you're running.
