Matthew Hughes shared with us an Arduino project to create a sketch to perform a musical tone version of the classic Arecibo “message of peace.” A friendly local version of what we have transmitted into space…:

A couple of weeks ago I came across an article about the Fermi Paradox while enjoying a cigar and beer on the porch. It explained several reasons why we have not made contact with an extraterrestrial civilization, even though there are theoretically millions in existence.

As I tend to do when coming across similar topics, I went on a reading frenzy. This led me to the Arecibo message, humanity’s first attempt to send a message to an extraterrestrial intelligence. This message was transmitted a single time from Puerto Rico’s Arecibo radio telescope in November 1974.

Space exploration and related research is fascinating to me, and it inspired me to create an Arduino circuit to mimic the transmission of the Arecibo message.
