Ruby and RaspberryPi are available to us for quite sometime and this talk ismeant to discuss how to use Ruby to explore things on a RaspberryPi. From apractical point of view, we will go through installation, setup, and build asimple Motion Sensor application on a RaspberryPi. In a world we teach ourselves a lot of things, why not do it Ruby & Pi way?Let’s get our hands on a piece of hardware, understand what it takes to setupone up, install a couple of libraries, Ruby, RVM, RBENV, a GUI. Let’s get acouple of sensors: motion, temperature, humidity, tsunami, ectoplasm and seeif we detect a cool thing or two.
