**1.** Connect a WS2812B-compatible RGB(W) led strip to you ESP board:

- For ESP32 use `GPIO16` (or `IO16` or `G16`); GPIOs `4`, `13` and `16-33` can be used, other pins are not recommended.

- For ESP8266 use `GPIO2`, on most development boards this pin is labeled `D4`.

_If the connecting wire cannot be kept short, use a [level shifter/translator](/basics/compatible-hardware#levelshifters)._ Optionally, connect a normally open pushbutton to `GPIO0` (NodeMCU/Wemos pin `D3`, on ESP32 use `IO17`) and ground for [configurable actions](/features/macros).

The N74(A)HCT127(N) can be wired in different ways. The diagrams show the easiest wiring by connecting unused inputs to GND and leaving unused outputs unconnected. In general:
