[Kyri] has made a simple circuit to do color detection using an RGB LED. Simply set the LED to the color you want to detect then wave the object over it. Another LED will light up if the object is the ...

Color vision, ocular color detection is achieved with complicated neural mechanisms in the eyes. Researchers have found color detection with a simplest mechanism in the fish pineal organ, an ...

Could you briefly describe your research project? We are working to develop a biomolecule sensing device that can detect the existence of a virus through color changes that people can see with the ...
