See if the RGB values shown in the serial monitor changes with different color or not.

Hi,
This module is for color detection, you can view the text results on the Serial Monitor after uploading the code.
The example code doesn’t include LED control. To light up the LEDs, just connect the module’s LED pin to an Arduino digital pin, GND to GND, and set that pin to HIGH in your code.
