Have we gone LED hacking crazy today? Yes, here’s a real simple way to make an RGB LED color detector, this might be a good project you can implement for your future devices.
Have you ever wanted an automated way to detect the color of an object? By shining light of a certain color on the object and looking at how much light is reflected back, you can tell what color the object is. For example, if you shine a red light on a red object, that light will be reflected back. If you shine a blue light on a red object, the object will absorb some of that light and less of it will be reflected back.
