This project runs on a Raspberry Pi and polls a Jenkins API URI periodically, displaying the last build status for a software development team to monitor the continuous integration status. This practice is described here: http://en.wikipedia.org/wiki/Build_light_indicator.
It displays the build status using a Pimoroni UnicornHat. This makes it a plug-and-play solution, requiring minimal setup, to display the status of a Jenkins build.
