In any case, one of the readers asked for a code in my previous instructable dealing with RGB LED strips connection to an Arduino, and I promised an article. What’s better suited to control such a thing than the red, green and blue color model? Why complicate matters by additional algorithms converting data from a very different set of rules to the native one? Still, HSV persists it’s even present in an excellent ShiftPWM library. Really, people! An RGB LED consists of three LEDs: red, green and blue. The most common strangeness is the use of the HSV color model for RGB LED programming. However, time and again I come upon projects using strange approaches to this matter. ![]() It would seem that such simple things as a rainbow effect or smoothly changing random colors on an RGB LED are pretty trivial.
