Sweeping the onboard RGB LED on GPIO48
|

```

If the firmware runs but the RGB LED remains dark, verify the board revision. The project defaults to GPIO48, commonly used by DevKitC-compatible boards and official v1.0 boards. For an official v1.1 board—or another board wired that way—change `RGB_LED_GPIO` in `platformio.ini` from `48` to `38`, rebuild, and upload again.
