I just connected power to this thing. Pro trinket, WS2812B leds, running Color Palette.

I just connected power to this thing. Pro trinket, WS2812B leds, running Color Palette.
It’s just flickering like crazy, when I press the reset on the trinket to stop the program, the colors stay solid, so I don’t think it’s a power issue. My current guess is the data line is shorted with 5v or ground somewhere.

Any input?

Well, I did more testing, and it does not seem to do this with a battery power source and Arduino pro mini. So it’s either going to be power, the trinket, or the program…

Definitely check the grounds. Do the controller and the LEDs share a ground?

They are not sharing it right now. I’ll join them. thanks

That’ll solve the problem

@Jeremy_Spencer That was definitely the issue. Thank you!

Looking forward to seeing it working properly :slight_smile:
