How do we get the green/blue lights flashing?

Getting the Arduino talking to LInux in order to program it? That’s easy (on Ubuntu at least). The Arduino.cc has a page on what you need to install – think it’s all in the Ubuntu repositories now. Not sure about other distros.

The Arduino has USB serial connection to laptop which just works in my experience.

Current Cost is linked by USB serial cable to a (Linux; though could be Windows) server in my house. On the server is an MQTT client, which publishes readings to an installation of IBM's Really Small Message Broker (but could in future be the open source Mosquitto) on an external server on the Internet somewhere (not hosted by me). Take a look at MQTT.org for more information about the MQTT brokers and clients. The MQTT client I use isn't freely available but there are others. Note that the Arduino MQTT client on that page is only for if you have an ethernet/wifi shield on your Arduino that can access the Internet directly. I don't use that because I connect my Arduino to my laptop and have an MQTT client on there too which can connect to the external server to subscribe to electricity readings. Which means I always have to have my laptop on when using the lights, of course. I'm not sure if all that makes sense but reply if not and I'll try to write a blog post explaining it more clearly.

How easy is it to get the Arduino to talk to Linux? I have just acquired a huge bag of LED’s, and fancy having a go at making one of these :- http://www.youtube.com/watch?v=81DjwWqE6Iw&NR=1&feature=fvwp

What do you use to link the current cost meter to the internet?

I’d like to come and talk about the RFID stuff I’ve been playing with, and I will if you can convince Cerys she wants to go.
