You can sense a lot of things with the right sensor, and [Nikhil Nailwal] is here to show us how to sense colors using a TCS230. The project is a simple demo. It displays the color and lights up an LED to correspond to the detected color.
If you haven’t seen the TCS230 before, it is a chip with an array of photosensors, for different light wavelengths. The controlling chip — an Arduino, in this case — can read the intensity of the selected color.

Are you a bit obsessive compulsive with
lots of certain things? We are too. Like Skittles! If you’re the kind of person who likes to sort their Skittles, you should seriously look into making your own 3D printed Skittles Sorter.
Built more to challenge his new 3D printer, [MrPrezident] was looking for a project to combine mechanical design with a bit of image recognition prowess — so he came up with this clever, and compact, Skittle sorting machine.
It uses an Arduino Uno with a ZITRADES color sensor module to identify the color of each candy. A small LED helps illuminate the Skittles to ensure an accurate color reading. Then, depending on the color, a series of gears rotate the Skittles piece to its designated color repository.
Theoretically it should also work with M&M’s (which are a bit smaller) but unfortunately, there are 6 colors of M&M’s and only 5 colors of Skittles. What would the machine do then!? We don’t see a reject bin!
