<br>Hi!<br><br>Looking for some advice for an art installation. I'd like to have a light or set of lights respond to an auditory<br>input. I'd like the lights to turn on in time with the sound of a ventilator (a medical one). So when the ventilator is<br>not doing a breath, the lights would be off, but then when the ventilator starts doing a breath they would<br>turn on for the duration of the breath. I'd like the lights to light up and dim gradually, not just on an off.<br><br>What's a simple or best way to do this?<br><br>Thanks!<br><br>Chris<br><br>_______________________________________________<br>Lab mailing list<br><a ymailto="mailto:Lab@artengine.ca" href="mailto:Lab@artengine.ca">Lab@artengine.ca</a><br>http://artengine.ca/mailman/listinfo/lab<br><br><br> </div> </div> </div></body></html>
