i have tried multiple versions of WLED and they used to light up yellow when you connect the string but mine is not doing anything. I have tried two different d1 minis and same output.
This is really boggling my mind it used to work so good and now its not outputting anything. the lights get the 5v i see it at the end of the string so im at a loss. i am on 1.14.0 right now but have tried the newest and some older versions. None of them are lighting anything up. i even reduced it to 10 LEDs.
Please only post questions once. Creating multiple threads for the same issue only confuses things.
See your other thread for more info.
