Pointing the Colorino and the remote for my 21-year-old Sanyo CRT color TV at each other and pressing different buttons on the remote. It has no trouble detecting the infrared light. Changing the angle just slightly makes a difference in the tone. They must be pointed right at each other at fairly close range.
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.
