# RGB LED Module
## Introduction  
<font style="background-color:rgb(253, 253, 254);">The RGB LED Module integrates 8 full-color LEDs and uses the WS2812 main control chip to achieve single-wire control. This design allows users to control all LEDs through a single signal pin, offering flexible manipulation. Additionally, by adjusting the RGB values precisely, users can display a wide range of vibrant colors. The brightness of the LED ring can be adjusted from 0 to 255, meeting various lighting needs.  </font>

> <font style="background-color:rgb(253, 253, 254);"></font>**Note:**<font style="background-color:rgb(253, 253, 254);"> Due to the high brightness output of the RGB LED Module, avoid prolonged direct exposure to the light source to prevent eye damage.  </font>

<font style="color:rgb(0,0,0);">To use the RGB LED Module, first initialize the port. Here, "strip" is the initial variable. Different variables can be set to correspond to different RGB LED modules on different ports. You can also adjust the corresponding brightness of the LED ring (0~255).  </font>
