How does the LED RBG led work?

Good evening, everybody. I’m trying to figure out how the RGB led works but I can’t figure it out. Who would be so good and kind to explain to me how it works and if after can get me a code (IDE program) with all the explanations?
I mean the LEDs with four cables. I don’t understand just how they work
Thanks again and good evening. :slight_smile:

OK, first you need to explain what you mean when you say "RGB LED", because there are many different sorts of them.


Most RGB LEDs have four terminals, albeit some have six.
