Remote is just another area, but the first is to detect the event including the cycle. <br></span></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: times new roman,new york,times,serif; background-color: transparent; font-style: normal;"><br><span></span></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: times new roman,new york,times,serif; background-color: transparent; font-style: normal;"><span>Ken<br></span></div> <div style="font-family: times new roman, new york, times, serif; font-size: 12pt;"> <div style="font-family: times new

If you can mod or attach a sensor to the ventilator where it will not be seen you could use and rf transmitter or an infrared led to send a signal to the light controller to sync the lighting to it. <br><br>Perhaps a piezoelectric sensor (old buzzer would do) stuck to the main body of the unit to pick up the vibration of the motor, transistor to amplify the small signal and drive an IR LED pointed up. Then the arduino could pick up the vibration of the unit by using an IR receiver diode. <br>This would cut out the microphone which maybe would be triggered falsely if it is to be installed in a noisy installation. <br><br>-Tony<br><br>Sent on the TELUS Mobility network with BlackBerry<br><br>-----Original Message-----<br>From: The Big Plan - Chris B <<a ymailto="mailto:tbp@ghostwise.com" href="mailto:tbp@ghostwise.com">tbp@ghostwise.com</a>><br>Sender: <a ymailto="mailto:lab-bounces@artengine.ca"

I'd like to have a<br>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<br>ventilator (a medical one). So when the ventilator is<br>not doing a breath, the lights would be off, but then when the<br>ventilator starts doing a breath they would<br>turn on for the duration of the breath. I'd like the lights to light<br>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"
