Yesterday we were at the Arduino Day 2014, organized by the WeMake association.
I must say that it was a really interesting afternoon, I particularly enjoyed two things: the presentation of Arduino Yùn (my reaction was: I want it), and one of the projects on display: MEG (Micro Experimental Growing), an open source greenhouse , which uses precisely Arduino. It is worth spending two minutes to watch the movie, because the project, in my opinion, is beautiful, and maybe contribute economically: you only need one pound.
