Does Arduino dream of a playing tree?
With the help from Lindsey French, some houseplants in Chicago have enjoyed a concert generated by the vibrations of a cherry tree in western Massachusetts.
Attached to the cherry tree was a piezo sensor, which measured the tree’s vibrations. These were uploaded to the world wide web using an Ethernet Pro as a server, and a friend’s wireless router, configured to allow port forwarding. On the chicago end, a processing sketch gathered the data and wrote it to the serial port my laptop. An Arduino attached to the laptop output the data to transducers, which were attached to ceramic saucers (and later, a plywood shelf) as the medium for the vibrations. The Arduino and breadboard were housed in a custom laser-cut box, based off of a modified thingverse template.
