Wich RGB? WS2812B or a single color rgb? If you have a WS2812B you can use the existing Lib from XOD To use you have to connect your Strip to D2 of Wemos board. In the Node you choose GPIO4 called (D4) When you use normal RGB you take PWM load node for each color. D5-\>PortD14 D6-\>PortD12 D7-\>PortD13 For this you need a N-Channel Mosfet to drive the Current of the strips per pwm. ![esp8266-WemosD1MiniPinout](https://canada1.discourse-cdn.com/flex027/uploads/xod/original/2X/5/54ad35ece0def4f620326eaa855dd71686752a91.png) Greez Chris ---
