The WS2812B (or “NeoPixel”) may look like a common 5050-sized (5x5mm) SMD LED, but there’s actually an integrated control circuit embedded inside there too. If you look really hard, you can see the tiny black chip hidden in there, along with minuscule gold wires connecting the chip to the LED. This LED is certainly more than meets the eye! The ‘B’ at the end of the WS2812 name denotes that these specific LEDs are equipped with and only require FOUR pins instead of SIX!
The LED itself is unlike most RGB (Red/Green/Blue) LEDs. The brightness of each color can be adjusted using a serial string to one of 256 different levels. That means there are 16,777,216 (2563) possible combinations of colors. You can produce any color from white to black (off), or salmon to sienna.

該WS2812B可能看起來像一個普通的5050尺寸（5x5毫米）SMD LED，但實際上有嵌入式裡頭有太多的集成控制電路。如果你看看真的很辛苦，你可以看到小黑點芯片藏在那裡，連接芯片到LED微小的金線沿。此LED肯定不止滿足眼睛！的“B”在WS2812名稱的末尾表示這些具體的LED配備有，只需要四個引腳代替六！
