ESP32-C6 RGB LED Control

Welcome to the ESP32-C6 built-in RGB LED Configuration Guide! This repository contains Arduino code for easily managing the built-in RGB LED on ESP32-C6 microcontrollers, perfect for IoT and embedded systems projects.

ESP32-C6 Board Overview

The image above shows the ESP32-C6 DevKitM-1 board. The built-in RGB LED is connected to GPIO 8, which is already configured in our code.

Key Features

• Easy control of the built-in RGB LED on GPIO 8
• Predefined color constants for common colors
• Simple function to set any RGB color
• Easily expandable to include more colors and patterns

Software Requirements

• Arduino IDE
• ESP32 board support for Arduino IDE
• Adafruit NeoPixel library

Installation

1. Install the Arduino IDE from arduino.cc
2. Add ESP32 board support to Arduino IDE:
   • Open Arduino IDE
   • Go to File > Preferences
   • Add the following URL to "Additional Boards Manager URLs":
     https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
   • Go to Tools > Board > Boards Manager
   • Search for "esp32" and install the latest version
3. Install the Adafruit NeoPixel library:
   • Go to Sketch > Include Library > Manage Libraries
   • Search for "Adafruit NeoPixel"
   • Install the latest version

Quick Start

#include <Adafruit_NeoPixel.h>

#define LED_PIN 8  // The ESP32-C6 pin connected to the built-in RGB LED
#define NUM_LEDS 1

Adafruit_NeoPixel rgbLed(NUM_LEDS, LED_PIN, NEO_GRB + NEO_KHZ800);

struct RGB {
    uint8_t r, g, b;
};

constexpr RGB COLOR_OFF = {0, 0, 0};
constexpr RGB COLOR_RED = {255, 0, 0};
// ... Add more color definitions here

void setup() {
    rgbLed.begin();
    rgbLed.show();
}

void setColor(const RGB& color) {
    rgbLed.setPixelColor(0, rgbLed.Color(color.r, color.g, color.b));
    rgbLed.show();
}

void loop() {
    setColor(COLOR_RED);
    delay(500);
    setColor(COLOR_OFF);
    delay(500);
}
    

Customization

• The LED_PIN is set to 8 for the built-in LED. Do not change this unless you're using an external LED.
• Add new color definitions in the RGB struct format
• Create new light patterns by combining setColor() function with different delays
• Modify the BLINK_DURATION to change the speed of the blinking pattern
• Create new light patterns by combining setColor() and blinkColor() function

Usage

1. Download the esp32_c6_rgb_led_control.ino file
2. Open the .ino file in Arduino IDE
3. Select your ESP32-C6 board from Tools > Board menu
4. Select the appropriate port from Tools > Port menu
5. Click the Upload button to flash the code to your ESP32-C6
