FAQ
Q: Can this be stripped to a red, green, and blue wire (+power) to be wired to a different board?
A:No, the WS2812 is a digital LED, it need to be controlled by a micro controller or AVR with a digital pin and appropriate library

Q: Does each led require 18ma so the total 24 * 18 ma or total 432ma ?
A: Yes, total is 24*18ma, this is for normal led brightness. You can also change code to change the led brightness, and the current will be different.
Q: Is this something I can program once and not require data in? I need to program all led red or green and then power down and up to the last color.
A: Yes, you can write code to achieve this function
