How should that work? Three color-filtered light sensors and A/D converters on the Ardunino? With optics to get some sense of where the sensors are "looking"? Or a full-blown video camera? But that's not very Arduino-friendly, and synthesizing three numbers from a whole image seems hard.
In general, I think the appeal of this solution is its simplicity, it could be implemented on something even smaller than the Arduino. Adding video processing would be a move in the opposite direction, I think.
- gojomo 11y agoTo me, the appeal of this device (and potential variants) is all in the new perceptive capabilities it grants the user – independent of any implementation details. So to send color, I'd say sure, add a cheap video camera and whatever optics/CPU/software that's necessary to read the color, out along the same line for which the distance is being measured.
