This is a very simple lesson I've done in Rome during the Arduino day on March 29th, 2014. You can go through my presentation, talking about the cultural, historical and social value of the IR power and protocols. The practical part It setups basic circuit for tseting one of the most common examples of the IRremote library by Ken Shirrif letting Arduino sniff a button and reproduce it by itself. The Cover of this lesson is an italian comic I've been reading in my teenage. It's called X Zone (Zona X, in italian) and is a side publication of Martin Myst辿re, the Impossible's Detective. The comic book has been written by Alfredo Castelli and drawn by Giancarlo Alessandrini, edited in italy by Sergio Bonelli. The link to the publication is not just a title matching my presentation but means a lot to me: most of the concepts, metaphors and ideas I've faced by reading this comic book are present in my daily thoughts today.
