WebJan 28, 2024 · One of the things that the FastLED library will do is attempt to use the fastest mechanism available to it for driving your leds. This stands out most clearly with SPI based chipsets (e.g. the APA102, WS2801, etc...). When you set up your leds, you give FastLED a data pin and a clock pin: FastLED.addLeds (leds,NUM_LEDS); Webhue = map8 ( sin8 ( myValue), HUE_BLUE, HUE_RED); Mathematically simiar to lerp8by8, but arguments are more like Arduino's "map"; this function is similar to. map ( in, 0, 255, …

WebJun 22, 2024 · The library provides fast, efficient methods for converting a CHSV color into a CRGB color. Many of these are automatic and require no explicit code. For example, to set an led to a color specified in HSV, you can simply assign a CHSV color to a CRGB color: // Set color from Hue, Saturation, and Value. WebJun 22, 2024 · FastLED allows you to cap the power usage of your leds. There's two ways to set the max power draw you want. The first is by specifying the voltage your leds will be running at and the maximum milliamps you want to draw: // limit my draw to 1A at 5v of power draw FastLED.setMaxPowerInVoltsAndMilliamps (5,1000); The other is to specify … how to make your nails grow slower
