ws2812b chips

Hello,i am just starting out with Arduino nano and I have questions about ws2812b leds.Can these chips be

programmed individually in a string? Let's say I have an octagon shape with 15 chips in it and I want to lite up one chip at a time of my choice not in any certain order. How would I do this and what would the programming look like? I can't seem to find any info on how this would work (for me to understand how).

thanks in advance for any info I can get. Great info for beginners on forums!


Hi lamar263, welcome !

Keyword is neopixel. As far as i know, Adafruit came up with that word and they do some real good explanation and tutorials.

There are examples that come with the neopixel and fastled libraries.
