What it does
Tweets are ranked by sentiment and an LED traffic light lights up momentarily, depending on the sentiment. The tweet, author and account image is then displayed on a front end. A PI Hat/ Colour LCD screen loops an animated gif.
The tweets themselves are stored in a MongoDb which feeds the front end, which refreshes itself every few seconds.
This page is not intended to be a tutorial but rather listing and showing things that are not deployed publicly.
