바이올린 ( Biolin : A Current-based Musical Interface ) Version 3.0

The hardware, which was comprised of an Arduino microcontroller,
detected the voltage passed through the Biolin. This data was
then passed to a computer via serial communication before
Processing processed the visualization and calculated the timbre
and pitch of the sound to create. The attributes of the sound was sent,
via the MaxLink library, to MAX/MSP, where the appropriate sound was outputted.
The visualization was implemented with Processing, which was also in charge of selecting
the appropriate timbre and pitch of the sound. Selection of the timbre was done
using the data collected during calibration. When calibrating, the user holds the Biolin
and moves it from one end to the opposite end, while keeping it in contact with the target
for five seconds. After doing so, the minimum and maximum voltage data is gathered
to select the most appropriate timbre that suits the target.

The Biolin is a violin bow, modified to pass weak electric current along where the hair is,
equipped with an Arduino board with sensors that collect the voltage data.
The modification involves nicrome wire coiled around the bow hair. The Biolin is connected
to a computer, which receives the data transmitted by the voltage sensors
and produces the appropriate visualization, timbre, and pitch.
