  • Hi, I am trying to make a backlight using WS2812b for my nixie clock project. Here is a screenshot:

    I am controlling 5v Neopixel with 3.3v logic. As you can notice, when the microcontroller pin is high, LED's data pin is 0v, when the pin is low, LED's data pin is 5v. AFAIK Espruino's Neopixel lib is designed for non-inverted wiring only. Is there a workaround for my case? Maybe the pin itself can be inverted, so it outputs HIGH when being set to LOW and vice versa. The PCBs are already printed and I don't want to throw them away
