This code controls 3 WS2812 RGB LEDs connected to GPIO 15 on an ESP32-S3.
Each LED will be set to blue with adjustable brightness.
The Adafruit NeoPixel library is used to communicate with the WS2812 LEDs.
Hardware setup:
- WS2812 RGB LEDs are connected to GPIO 15 (data pin).
- Total number of LEDs: 3.

Parameters:
- n: The LED number (starting from 0).
- c: The color to set the LED to, in hexadecimal (0x0000ff = blue in RGB format).
