That is so cool Doc!... You have a link for those sound sensors?

Robot-Doc, Now we know what Roombas are really thinking! Very cool work. Do you have links on the sound sensor and L.E.D.s? Thanks for sharing your video. Steve S

Here is the link for the Sound Sensor

For some reason there is no link for the little circle flashing LEDs.

OK, found the same style of flashing leds but they are on a larger PCB.

Its hard to read Chinese converted to English... Am I correct in assuming that it drives the brightness of LEDs (or other) depending on the audio wired through it or does it have a mic that picks up the audio level that way?

From what I can tell there is a sensor inside the little plastic box and the sensitivity to sound is adjusted by a small knob.

So if you clapped your hands or a dog barking or just any fairly load ambient noise would trigger it? Ok, I am sold going to grab one...

Thanks Doc

Richard R - the sensor is powered using 12vdc so the output that is switched on when sound triggers it is also 12vdc. It's kinda like whatever voltage is used to power the sound sensor is also the voltage that is present on the output connector.

Awesome
