Twitter scrape and count triggers signal

README.md

This flow searches Twitter for certain hashtags (in this case water and fail), pushes the Tweet to an output and counts the number of Tweets retrieved. After 5 Tweets, it triggers a signal and resets the counter. It's part of a project that will grow, which will interact with an RPi to control a valve to release water on an accumulation of Tweets.
