I am trying to control a WS2812B Led Strip with my ESP-01S board. It works fine with my ESP32 DevKit board, but the ESP-01S won't do anything :/ I couldn't figure out which 2 GPIO the ESP-01S is using (from the pinout), I assume it's GPIO0 (pin 5) and GPUI1 (pin 2). I modified the sketch and tried several pin settings but the LED won't react. any ideas what's wrong?

  • io 0 and io 2 are on every esp-01 header
