Once the sensors are in place and your board is publishing data to an MQTT broker, the next steps are to aggregate, display and action. I recommend you try a free account with cloud9 (https://c9.io/c/mdINlHY8cba) and developing in YAML (https://en.wikipedia.org/wiki/YAML) with MeteorKitchen (http://www.meteorkitchen.com/).
Cloud9 offers hosted workspaces pre-configured for many common programming platforms and I chose Node.js. Right there in your browser you will see a fully-functional IDE running within a configured Ubuntu instance. In my C9 workspace console I installed Meteor, MeteorKitchen and JSON-YAML parser:
curl https://install.meteor.com/ | sh
curl http://www.meteorkitchen.com/install | /bin/sh
npm install -g js-yaml
There are many examples shown in MeteorKitchen, but as we are discussing IoT, lets take a look at:
The result? – a working reactive web app showing live sensor data, written in 44 lines of code. Enough said, go try!
