Holding the Colorino up against the screen of my LG328BG cellphone. It produces a pure tone, no detectable modulation. The first step up in frequency was when I woke it up, the much stronger reaction was when I unlocked the screen. 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.
