In this tutorial, a color sorting machine is made using a TCS3200 color sensor, servo motors, and an Arduino board. The machine sorts colored balls and places them in the relevant color box.
The TCS3200 color sensor can detect multiple colors with proper programming. It contains RGB arrays, which are visible as square boxes under a microscope. Each box has three sensors: one for red light intensity, one for green light intensity, and one for blue light intensity.
The module can be featured to sense a particular color and ignore others, using filters for selection purposes.
