I kicked off another Halloween project this year and I posted it on GitHub for everyone to see and use if they like. This project has focused around building smart devices that are all connected via an MQTT bus. I wanted to have something that I could build on every year. The devices are either actuators or sensors that are smart enough to serve a purpose and can be orchestrated into a bigger animation scene using a workflow engine such as Node-red. Anyways check out the project on Hackster.io and GitHub.
