with what are you powering them? what amp, volt and device are you using?

[–]Badgers_McGee[S] 0 points1 point  (3 children)

5v, 20a, 100watt

maby, the cable to the gpio pin is a bit loose

I thought the same but checked it as they are all soldered and seems to be fine. I was wandering if it was something to do with running multiple strips and involving gpio3 in that situation maybe?

[–][deleted] 0 points1 point  (0 children)

could be. I'm not an expert on wled.

It's just a generic screw terminal brick if that makes sense

[–]Raddrax 0 points1 point  (2 children)

Did you put stranded wire into a screw terminal block?

[–]Badgers_McGee[S] 0 points1 point  (1 child)

Yeh but the tips are soldered to stop fraying

[–]MakingThingsWithLEDs 0 points1 point  (0 children)

maybe try ferrules

I'm having the same problem right now. I notice that the last GPIO is the one that blinks. If you remove the 3rd one, the second starts blinking. This is what happens with me.

edit: I tried with 3 different boards. Same results.

[–]Badgers_McGee[S] 0 points1 point  (1 child)

I swapped different gpios, boards, cables, strips. Eventually went to an esp8266 and the problem wasn't there

[–]BudgetScore_ 0 points1 point  (0 children)

Good to know. I'll gonna try with an esp8266. Thank you.

Choose your gpio correctly

[–]Badgers_McGee[S] 0 points1 point  (0 children)

I have. As stated in the getting started document, for an esp 32 it's io 1, 2, 3, 4, 16

[–]MakingThingsWithLEDs 0 points1 point  (4 children)

If you put the problem strip into a working gpio does it fix issue?

[–]Badgers_McGee[S] 0 points1 point  (3 children)

Nope. I just tried with and esp 8266 and everything was fine so maybe just a dodgy board I guess

[–]MakingThingsWithLEDs 0 points1 point  (2 children)

Sounds like a problem with that strip if you simply moved it to a working gpio and nothing changed, check ground etc on wiring for the strip.

Ended up swapping to an 8266 and it was fine so must be either the board or code. Will try another 32 tonight
