[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 ...

When you need to quantify the color of an object, you’ve got quite a few options. You can throw a Raspberry Pi camera and OpenCV at the problem and approach it through software, or you can buy an ...

The color detection circuit is capable of determining the color of an object using RGB LED. The process takes place by shining light of a certain color on the object and the color of the object can be ...

[Editor's note: this is the second installment in a relatively large project. The engineering challenge faced by these students was to create a talking color detector. I've elected to print the entire ...

How sensors are driving predictive maintenance. How maintenance is traditionally performed and the importance of moving to a data-driven approach. An overview of how sensors are the eyes and ears of ...
