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> slainte mhath, RGB<br><br>--<br>Richard Guy Briggs -- ~\ -- ~\ <<a target="_blank" href="http://hpv.tricolour.net/">hpv.tricolour.net</a>><br><<a target="_blank" href="http://www.tricolour.net/">www.TriColour.net</a>> -- \___ o \@ @ Ride yer bike!<br>Ottawa, ON, CANADA -- Lo_>__M__\\/\%__\\/\%<br>Vote! -- <greenparty.ca>_____GTVS6#790__(*)__(*)________(*)(*)_________________<br><br><br> </div> </div> </div></body></html>
