The Nova Mini project suite consists of two main components that work together to create an interactive memory game experience:

1. Nova Mini (Receiver)
2. Nova Mini Remote (Sender)

These devices communicate wirelessly using ESP-NOW protocol to create an engaging, interactive game experience based on the classic Simon memory game.

The main game controller that:

• Handles core game logic and state management
• Controls LED patterns and audio feedback
• Processes player inputs
• Manages game progression through levels and rounds
• Provides hardware-level control and feedback

The user interface controller that:

• Initiates game commands and controls
• Sends instructions to the Nova Mini receiver
• Provides real-time game state updates
• Offers enhanced game mode features
• Enables remote gameplay control

Both devices are built on the ESP32 platform, featuring:

• ESP32 microcontroller
• LED indicators for visual feedback
• Push buttons for user input
• Buzzer for audio feedback
• Custom PCB design

Built using modern embedded development tools and frameworks:

• PlatformIO development environment
• Arduino framework for ESP32
• ESP-NOW protocol for wireless communication
• Custom libraries:
  • ESPUI for web interface
  • AsyncWebServer for configuration
  • MIDI Library for audio control
  • ArduinoJson for data serialization
  • OneButton for enhanced button control

The devices use ESP-NOW, a connectionless wireless communication protocol that enables:

• Low-latency communication
• Peer-to-peer data exchange
• Efficient power usage
• Reliable message delivery

• Multiple difficulty levels and progressive rounds
• Real-time LED and audio feedback
• Enhanced state management with stages:
  • Sequence Generation
  • Input Collection
  • Verification
  • Round Transition
  • Game Win/Loss states
• Remote control capabilities
• Cheat mode for testing

The system includes a web-based configuration interface that allows:

• ESP-NOW pairing between devices
• MAC address management
• Game mode settings
• System preferences

This project is built using PlatformIO, offering:

• Cross-platform development
• Integrated dependency management
• Automated builds
• Extensive debugging capabilities
• Serial monitoring at 921600 baud
