Hey.. great ible.. I went thorough your ible for detecting colours too.. But I still have a basic question- why do you use leds to provide light which then reflects from the surface (to be colour sensed)? While writing this question I'm guessing it is to increase the dimensions or channels from 1 to 3. But can you please elaborate a bit on it (if it is correct)Sorry if it is already answered, but the science kept bothering me.
