TCS3200D-TR Colour Sensor IC

/*
The TCS3200 is a color sensor that can detect and measure the intensity of individual red, green, and blue (RGB) channels. Here's an example of how to use the TCS3200 with an Arduino to read the RGB values and display them on the Serial Monitor:

To wire the TCS3200 sensor, connect its VDD pin to the 5V pin on the Arduino and the GND pin to the ground. Connect the S0, S1, S2, S3, and OUT pins to the corresponding pins on the Arduino as defined in the code (S0 to pin 8, S1 to pin 9, S2 to pin 12, S3 to pin 11, and OUT to pin 10).

This code will continuously read the RGB values and print them on the Serial Monitor. Note that the TCS3200 measures the intensity of each color channel separately, so you'll need to do additional processing to convert these values into a standard RGB color representation or other color spaces like HSV.

Make sure the TCS3200 sensor is properly placed over the object whose color you want to detect. You can also adjust the scaling array according to the TCS3200 datasheet if you need different frequency scaling settings.
