        button.resetButton();
    }
}
```

### V2 (4-Button)
```cpp
void loop() {
    if (led.isReady()) led.runAutoLight(runAutoLightCallback);

        if (button.isPressed(i)) {
            button.resetButton(i);
        }
    }
}
```

### V3 (Advanced)
```cpp
void loop() {
    if (led.isReady()) {
        led.runAutoLight([](uint32_t sequence) {
            // Advanced callback with sequence info
        });
    }
    
    for (int i = 0; i < 4; i++) {      // Multi-button support
        if (button.isPressed(i)) {
            button.resetButton(i);
        }
    }
    
    cmd.process();                     // Serial command processing
}
```

## 🚀 Migration Guide

### V1 → V2 Migration
**Effort**: ⭐ Minimal (2-4 hours)

**Required Changes**:
```cpp
// 1. Add additional button pins
const int ON_INT_PIN = 34;
const int OFF_INT_PIN = 17;
const int NEXT_INT_PIN = 36;
const int PREV_INT_PIN = 39;

// 2. Update button attachments
button.attach(0, ON_INT_PIN, INPUT_PULLUP, FALLING, []() [[IRAM_ATTR]] -> void {
    button.readInterrupt(0, []() -> void { led.onMode(); });
});
// ... add 3 more button attachments

// 3. Update loop for multiple buttons
for (int i = 0; i < 4; i++) {
    if (button.isPressed(i)) {
        button.resetButton(i);
    }
}
```

### V2 → V3 Migration  
**Effort**: ⭐⭐⭐ Significant (1-3 days)

**Required Changes**:
```cpp
// 1. Add new components
SerialCommander cmd;

// 2. Replace manual config with dynamic
config.setDynamicDistribution(12, 2, 6, 6);  // Instead of readChannel()

// 3. Add smart button system
led.setButtonMode(BUTTON_MODE_1BUTTON);
led.enableSequenceMapping(true);
led.setActiveSequences(6, 0, 1, 4, 5, 8, 10);

// 4. Replace manual web server with APIServerManager
led.enableWebServer(true);  // Instead of manual initServer()

// 5. Add SerialCommander
cmd.init(&led, &config, nullptr, &button);
cmd.initWiFiAP();

// 6. Update loop
cmd.process();  // Add in loop()
```

### V1 → V3 Direct Migration
**Effort**: ⭐⭐⭐⭐ Major (3-7 days)

Combine both migration steps above plus additional architectural changes.

## 💡 Key Evolutionary Features V3

### 1. Smart Button System
- **Single pin**: Reduces hardware complexity
- **Multi-modal**: 1/2/3/4 button modes configurable
- **Intelligent**: Context-aware button behavior

### 2. Dynamic PCF Distribution
```cpp
// Auto-calculate optimal PCF distribution
config.setDynamicDistribution(total_channels, num_pcf, channels_per_pcf...);

// Strategies available:
- DISTRIBUTE_BALANCED   // Even distribution
- DISTRIBUTE_OPTIMIZED  // Minimize PCF usage
- DISTRIBUTE_SEQUENTIAL // Fill sequentially
```

### 3. Sequence Mapping System
```cpp
// Filter and reorder available sequences
led.enableSequenceMapping(true);
led.setActiveSequences(6, 0, 1, 4, 5, 8, 10);  // Only show these modes
```

### 4. Serial Commander CLI
```bash
# Multi-level access control
activate safe        # Enable LED control
activate full        # Enable hardware testing

# LED control
led 5 on            # Direct channel control
seq 8               # Set sequence mode
pcf scan            # Hardware diagnostics
```

### 5. PCF8574 Hardware Development
```cpp
// Test with PCF8574 hardware
// PCF8574 hardware will be automatically detected via I2C scan
```
