Moving the Colorino around near an LED nightlight I borrowed from the bathroom. LED's have some seriously strange modulation. This one's brighter than the average LED that shows your electronic device is on, but not as bright as the 4-watt incandescent nightlight we used to have. It doesn't seem to have a discernable attack and fade when turned on and off, but who can really tell with that crazy woop woop modulation. How can anybody look at that! The Colorino Talking Color Identifier and Light Probe produces a tone when you hold down the light probe button. It's a pocket sized 2-in-1 unit, which is a Color Identifier/Light Detector for the blind and colorblind. The stronger the light source, the higher the pitch. The more light it receives, the higher the pitch. So you can vary the pitch by moving and turning it. Recorded from line-in on my desktop using Goldwave. Low-pass filter was applied to lock out the 16khz sampling frequency.
