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>
