Well First project was working, got a string of ducks to listen for a MQTT subscription.
However as soon as I took the picture it broke. It seems to be a linux thing. Will fix it soon.
Just need to work out what to do with them when they work.
This works with an Arduino that takes a serial hex code that triggers the LEDs on or OFF. I have a perl script that works on my server and listens for MQTT subscriptions on Ducks. I got the Arduino code from “Making things talk” (link) it is a great book on the basics of Arduinos and networking with them.
