C6SuperMiniRgbLedLibrary

A simple Arduino library for controlling RGB LEDs on ESP32 C6 Super Mini devices using Adafruit NeoPixel.

Features

• Easy RGB LED control with predefined colors
• Brightness management (percentage-based)
• Support for multiple LED strips
• Built on Adafruit_NeoPixel library
• Optimized for ESP32 C6 Super Mini

Installation

PlatformIO

Add to platformio.ini:

lib_deps =
    https://github.com/trailcurrentoss/C6SuperMiniRgbLedLibrary.git@0.0.1

Arduino IDE

1. Clone this repository to your Arduino libraries folder
2. Restart Arduino IDE
3. Include the library in your sketch: #include <RgbLed.h>

Dependencies

• Adafruit NeoPixel

Quick Start

#include <RgbLed.h>

// Initialize RGB LED on GPIO 8 with 1 LED
RgbLed statusLed(8, 1);

void setup() {
  statusLed.begin();
  statusLed.setBrightnessPercent(50);  // 50% brightness
}

void loop() {
  statusLed.red();
  delay(1000);

  statusLed.green();
  delay(1000);

  statusLed.blue();
  delay(1000);

  statusLed.off();
  delay(1000);
}

Available Colors

• red() - Red
• green() - Green
• blue() - Blue
• purple() - Purple
• yellow() - Yellow
• aqua() - Aqua
• orange() - Orange
• off() - Turn off LED

API Reference

Constructor

RgbLed(uint8_t pin, uint8_t numLeds = 1)

Parameters:

• pin: GPIO pin number connected to LED data line
• numLeds: Number of LEDs in strip (default: 1)

Methods

void begin()                          // Initialize LED strip
void setBrightnessPercent(uint8_t)    // Set brightness 0-100%
void off()                            // Turn off LED
void red()                            // Set LED to red
void green()                          // Set LED to green
void blue()                           // Set LED to blue
void purple()                         // Set LED to purple
void yellow()                         // Set LED to yellow
void aqua()                           // Set LED to aqua
void orange()                         // Set LED to orange

Hardware Setup

ESP32 C6 Super Mini Connections

Signal	Pin
LED Data	GPIO 8 (configurable)
LED VCC	3.3V or 5V
LED GND	GND

Note: WS2812B LEDs typically require 5V power but work with 3.3V data signals.

Example Use Cases

Status Indicator

RgbLed statusLed(8, 1);

void indicateStatus(Status status) {
  switch (status) {
    case STATUS_OK:
      statusLed.green();
      break;
    case STATUS_WARNING:
      statusLed.yellow();
      break;
    case STATUS_ERROR:
      statusLed.red();
      break;
  }
}

Brightness Control

RgbLed brightnessDimmableLed(8, 1);

void setup() {
  brightnessDimmableLed.begin();
}

void loop() {
  // Fade from 0% to 100% brightness
  for (int i = 0; i <= 100; i += 10) {
    brightnessDimmableLed.green();
    brightnessDimmableLed.setBrightnessPercent(i);
    delay(100);
  }
}
