I do love a good demo. The folks at PubNub have been showing users of their software how home automation with a Raspberry Pi works – on a itty-bitty scale, with LEGO. This little house is rigged up with seven embedded LEDs (representing things like the stove and the fireplace, as well as lights); sensors to measure humidity, barometric pressure, and temperature; and a stepper motor that remotely opens and closes the door
