RGB LED SMD

/*
  BuiltByTyler Sensor Kit - S32 RGB LED SMD (5050 RGB)
  Board: ESP32-WROOM-32 DevKit V1 (30-pin), Arduino-ESP32 core 3.x, "ESP32 Dev Module"

  Cycles the wide-angle SMD RGB LED through colours with PWM.

  Wiring (module pin -> ESP32 pin):
    GND  -> GND
    R    -> GPIO 25
    G    -> GPIO 26
    B    -> GPIO 27

  Library: none needed
  Serial Monitor: 115200 baud
