Those of you that loved to watch the spy or detective drama series, you must be amazed by the high tech color detection weapon/device that being used in the TV screen, isn’t it? Would you believe, if someone tells you that you can develop a compact-sized color detection circuit in within few hours?
Frankly, it wasn’t some kind of joke, as you can really do it by your own. Oh, it seems that you’re wondering, “What can I do with this color detection circuit?” Well, good question!
For your curiosity, you can use the color detection circuit to detect the color of an object.
This is how the circuit works:
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! Ok, let say, if you’re shining a red light on a red object, that light will be reflected back instantly. Ok, now you’ve changed the color into blue, where you’re shining it on a red object, the object will absorb some of that light and less of it will be reflected back!
This color detection circuit is an awesome device, where it can be used for sorting in robotics without any hassle. Love it or hate it, you make the decision…
