Node-RED Twitter Workshop

These Node-RED flows use Twitter to introduce a variety of Node-RED visual programming techniques and simple ways to use the powerful Watson Cognitive services.

These Twitter Node-RED recipes showcase:

A simple flow that watches a Twitter feed.
Perform Sentiment analysis of Tweets. You could retweet positive tweets or SMS tweets to your friends
Perform Tone analysis of Tweets using the Watson Tone Analyzer service
Speak Tweets using the Watson Text to Speech service
Store Tweets and Sentiment scores in a Cloudant database for historical analysis
Build a Node-RED Dashboard that charts Twitter hashtag sentiment history
Perform Image analysis of pictures attached to Tweets using the Watson Visual Recognition service
Build a Nutrition Image Analysis dashboard to report the ingredients and nutritional information from the USDA
- Tweet a picture of food and use the Watson Visual Recognition custom food classifier. Great fun!

You might want to learn from the Node-RED Twitter workshop that I wrote to teach Node-RED and Watson Cognitive services. Follow the step-by-step instructions to create all of these example flows.
