+# NeoPattern Service for Spore Framework
+
+This example demonstrates how to integrate a NeoPixel pattern service with the Spore framework. It provides a comprehensive LED strip control system with multiple animation patterns and REST API endpoints.
+
+## Features
+
+- **Multiple Animation Patterns**: Rainbow cycle, theater chase, color wipe, scanner, fade, and fire effects
+- **REST API Control**: Full HTTP API for pattern control and configuration
+- **Real-time Updates**: Smooth pattern transitions and real-time parameter changes
+- **State Management**: Persistent state with JSON serialization
+- **Spore Integration**: Built on the Spore framework for networking and task management
+
+## Hardware Requirements
+
+- ESP32 or compatible microcontroller
+- NeoPixel LED strip (WS2812B or compatible)
+- Appropriate power supply for your LED strip
+
+## Configuration
+
+Edit `config.h` to configure your setup:
+
+```cpp
+#define NEOPIXEL_PIN 4              // GPIO pin connected to LED strip
+#define NEOPIXEL_LENGTH 8           // Number of LEDs in your strip
+#define NEOPIXEL_BRIGHTNESS 100     // Initial brightness (0-255)
+#define NEOPIXEL_UPDATE_INTERVAL 100 // Update interval in milliseconds
+```
+
+## API Endpoints
+
+### Status Information
+- `GET /api/neopattern/status` - Get current status and configuration
+- `GET /api/neopattern/patterns` - List available patterns
+
+### Pattern Control
+- `POST /api/neopattern` - Control pattern parameters
+  - `pattern`: Pattern name (none, rainbow_cycle, theater_chase, color_wipe, scanner, fade, fire)
+  - `color`: Primary color (hex string like "#FF0000" or "0xFF0000")
+  - `color2`: Secondary color for two-color patterns
+  - `brightness`: Brightness level (0-255)
+  - `total_steps`: Number of steps for patterns
+  - `direction`: Pattern direction (forward, reverse)
+  - `interval`: Update interval in milliseconds
+
+### State Management
+- `POST /api/neopattern/state` - Set complete state via JSON
+
+## Example API Usage
+
+### Set a rainbow cycle pattern
+```bash
+curl -X POST http://esp32-ip/api/neopattern \
+  -H "Content-Type: application/x-www-form-urlencoded" \
+  -d "pattern=rainbow_cycle&interval=50"
+```
+
+### Set custom colors for theater chase
+```bash
+curl -X POST http://esp32-ip/api/neopattern \
+  -H "Content-Type: application/x-www-form-urlencoded" \
+  -d "pattern=theater_chase&color=0xFF0000&color2=0x0000FF&brightness=150"
+```
+
+### Set complete state via JSON
+```bash
+curl -X POST http://esp32-ip/api/neopattern/state \
+  -H "Content-Type: application/json" \
+  -d '{
+    "pattern": 3,
+    "color": 16711680,
+    "color2": 255,
+    "totalSteps": 32,
+    "brightness": 128
+  }'
+```
+
+## Available Patterns
+
+1. **none** - Static color display
+2. **rainbow_cycle** - Smooth rainbow cycling
+3. **theater_chase** - Moving dots with two colors
+4. **color_wipe** - Progressive color filling
+5. **scanner** - Scanning light effect
+6. **fade** - Smooth color transition
+7. **fire** - Fire simulation effect
+
+## Building and Flashing
+
+1. Install PlatformIO
+2. Configure your `platformio.ini` to include the Spore framework
+3. Build and upload:
+
+```bash
+pio run -t upload
+```
+
+## Integration with Spore Framework
+
+This service integrates with the Spore framework by:
+
+- Extending the `Service` base class
+- Using `TaskManager` for pattern updates
+- Registering REST API endpoints with `ApiServer`
+- Following Spore's logging and configuration patterns
+
+The service automatically registers itself with the Spore framework and provides all functionality through the standard Spore API infrastructure.
+
+## Customization
+
+To add new patterns:
+
+1. Add the pattern enum to `NeoPatternService.h`
+2. Implement the pattern logic in `NeoPattern.cpp`
+3. Add the pattern updater to `registerPatterns()` in `NeoPatternService.cpp`
+4. Update the pattern mapping in `nameToPatternMap`
+
+## Troubleshooting
+
+- **LEDs not lighting**: Check wiring and power supply
+- **Patterns not updating**: Verify the update interval and task registration
+- **API not responding**: Check network configuration and Spore framework setup
+- **Memory issues**: Reduce LED count or pattern complexity
+
+## Dependencies
+
+- Spore Framework
+- Adafruit NeoPixel library
+- ArduinoJson
+- ESP32 Arduino Core

-# Static Web Server Example
-
-This example demonstrates how to serve static HTML files from LittleFS using the Spore framework.
-
-## Features
-
-- Serves static files from LittleFS filesystem
-- Beautiful web interface with real-time status updates
-- Responsive design that works on mobile and desktop
-- Automatic API endpoint discovery and status monitoring
-
-## Files
-
-- `main.cpp` - Main application entry point
-- `data/index.html` - Web interface (served from LittleFS)
-
-## Web Interface
-
-The web interface provides:
-
-- **Node Status** - Shows uptime and system information
-- **Network Status** - Displays WiFi connection status
-- **Task Status** - Shows active background tasks
-- **Cluster Status** - Displays cluster membership
-- **API Links** - Quick access to all available API endpoints
-
-## Building and Flashing
-
-### Build for D1 Mini (recommended for web interface)
-
-```bash
-# Build the firmware
-pio run -e d1_mini_static_web
-
-# Flash to device
-pio run -e d1_mini_static_web -t upload
-```
-
-### Upload Files to LittleFS
-
-After flashing the firmware, you need to upload the HTML files to the LittleFS filesystem:
-
-```bash
-# Upload data directory to LittleFS
-pio run -e d1_mini_static_web -t uploadfs
-```
-
-## Usage
-
-1. Flash the firmware to your ESP8266 device
-2. Upload the data files to LittleFS
-3. Connect to the device's WiFi network
-4. Open a web browser and navigate to `http://<device-ip>/`
-5. The web interface will load and display real-time status information
-
-## API Endpoints
-
-The web interface automatically discovers and displays links to all available API endpoints:
-
-- `/api/node/status` - Node status and system information
-- `/api/network/status` - Network and WiFi status
-- `/api/tasks/status` - Task management status
-- `/api/cluster/members` - Cluster membership
-- `/api/node/endpoints` - Complete API endpoint list
-
-## Customization
-
-To customize the web interface:
-
-1. Modify `data/index.html` with your desired content
-2. Add additional static files (CSS, JS, images) to the `data/` directory
-3. Re-upload the files using `pio run -e d1_mini_static_web -t uploadfs`
-
-## File Structure
-
-```
-data/
-├── index.html          # Main web interface
-└── (other static files) # Additional web assets
-```
-
-The StaticFileService automatically serves files from the LittleFS root directory, so any files placed in the `data/` directory will be accessible via HTTP.
