Ensuring Correct Wiring with a PI0W and WS2815 LEDs

  • Hello!


    So I cannot seem to get any response from my WS2815 LEDs when I connect them to my PI 0. I am a Computer Science major and not very experienced in electrical work like this so I have a feeling that I have wired this incorrectly. I've got the PI 0 with HyperBian running perfectly. Here are some of the HyperBian configurations:
    Controller Type: ws281x

    LED Count: 240

    RGB Byte Order: RGB


    Here is a quick summary schematic of what I have tried to no avail:


    This will use a 12V power supply to power the LEDs while I power the PI 0 with the normal method of a 5V 1A AC adapter to Micro-USB to simplify the project. I then use the step converter to turn the 3.3V signal given by GPIO 18 to a 5V signal for the LEDs.

    I don't want to fry anything accidentally so if I could get some pointers to help me get this working that would be great!


    Parts List:

  • SN74AHCT125 is a good Level shifter.


    The common ground is missing.
