WebDec 24, 2024 · I have a lamp based on Arduino with moving rainbow effect via FastLED library. The code is: void rainbow () { hue += 2; for (int i = 0; i < NUM_LEDS; i++) leds [i] = CHSV ( (byte) (hue + i * float (255 / NUM_LEDS)), 255, 255); } So I don't really like blue gradient in my rainbow so I'd like to remove it (i guess it's from 135 to 180). arduino WebConvert HSV to RGB using spectrum. Convert hue, saturation, and value to RGB. This ‘spectrum’ conversion will be more green & blue than a real ‘rainbow’, and the hue is specified just in the range 0-191. Together, these result in a slightly faster conversion speed, at the expense of color balance.
