How to use fastled for color utility functions?
A variety of functions for working with color, palletes, and leds. More… fill_gradient – fill an array of colors with a smooth HSV gradient between two specified HSV colors. More… A variety of functions for working with color, palletes, and leds.
What is the function fill _ gradient in fastled?
This function lets you specify which way you want the hue gradient to sweep around the color wheel: The default is SHORTEST_HUES, as this is nearly always what is wanted. fill_gradient can write the gradient colors EITHER (1) into an array of CRGBs (e.g., into leds [] array, or an RGB Palette) OR (2) into an array of CHSVs (e.g. an HSV Palette).
How is the hue function used in fastled?
Since ‘hue’ is a value around a color wheel, there are always two ways to sweep from one hue to another. This function lets you specify which way you want the hue gradient to sweep around the color wheel:

What is fastled library for Arduino LED strips?
This post provides a quick tutorial on how to set up an LED strip and some of the basics of the library. What is it? “FastLED is a fast, efficient, easy-to-use Arduino library for programming addressable LED strips and pixels such as WS2810, WS2811, LPD8806, Neopixel and more.
What do flashing lights do in fastled library?
Flashing lights are cool and all, but let’s make things move around! For this example, let’s make a single pink dot travel from one side of the strip to the other. Each pixel turns on, then off, then the program moves onto the next pixel.
How is the 7th led represented in fastled?
Each LED is represented in the array, so to access the 7th LED, we would use leds [6] (Array’s initial value is always 0). FastLED has an immense color library built-in, meaning, we don’t need to use RGB values, and can use named colors instead! Let’s make the 7th pixel blue to begin.
