Pointing the Colorino and my DirecTV remote at each other. the modulated light sounds similar to what you hear when you put a remote near an AM radio to hear it's processor. Yes, it does pick up near infrared light, and even will react to a space heater. I'll upload the AM radio bit at a later date. Repeatedly pressing the volume buttons which makes the remote talk to the old Sanyo TV. It sounds a bit different from when the Sanyo remote does it, there's a little fast DirecTV blip at the beginning, maybe telling the DirecTV box to ignore the next command "I'm gonna talk to the Sanyo now". It's a bit of a trick getting the units lined up perfectly, so the pitch will vary. I made it do that anyway to give you a good example of what it sounds like at many different light levels.
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.
