Which GPIO is used for seconds output on ESP32 ?
Thanks

There are lots of possibilities, checkout ESP32 pinouts for a table of the choices (look for Green outputs with no described issues).
Just update the WLED config with what you choose.

Your board may or may not have similar numbering, do you have a board (or one in mind)?

Thanks, I already played with esp8266. I am making stilts walking costume with almost 2000 leds. Before I played with 4 esp8266 and sync (2x legs 2x hands). With esp32 I will make one GPIO in parallel for hands, another one for legs.

If you check the link I sent, that is specifically for the ESP32.

Looks like a neat project.

You can safely use the same 5V supply for both the ESP32 and the levelshifter as the shifter uses very little power. Just make sure you’re using one of the types suggested in the KB: Level Shifters If you use a 74AHCTxxx type, you only need 5V.
