An installation in Palm House, Royal Botanic Garden, Edinburgh, Scotland where a variety of traditional Chinese instruments and chimes are controlled robotically in response to people and plants. The sounds produced by this are incredibly beautiful, watching the video of the installationis highly recommended. Built using Arduino, the installation reacts to the presence of humans and changes in the soil of the plant beds.
Similar and equally cool—Botanicalls, an open-source project that uses sensors to determine when plants need to be watered and then automatically calls its owner to ask to be watered.
