This project is a part of experiments done while doing an artist in residence at Instructables. You can see the other projects here.
Making a plant sing has been a trick since the Theremin was invented. Here I am going to teach you how to do this with and arduino board, a gameduino
shield and a the touch shield from my previous instructable
.A short introduction to capacitance
If two objects are conductive you can measure the capacitance between them (e.g. objects like: metal, water, human bodies and plants). By connecting a capacitance sensor to a plant we can detect if people are touching it and convert the touch into sound. Normally you would do this with a theremin like interface.
With the introduction of the touché frequency principle by Disney Research lab we can now make a really stable solution that can run entirely on the Arduino platform. The Touché works on a similar principle as a normal theremin, but does a frequency sweep instead. By hooking the touché up to the plant we can measure the capacitative interaction and convert it into sound.Credits:
The singing plant as an artistic project has been done with multiple people as a member of illutron. I will just credit af few key people who I have worked with: Åsmund Boye Kverneland, Nicolas Padfield, Thomas Jørgensen, Schack Lindemann, Thor Lentz, DZL, Vanessa Carpenter
