IoT Lotus Lanterns

The IoT Lotus Lanterns project is a network of wirelessly connected decorative lanterns, inspired by the elegance of lotus blossoms and powered by ESP32 microcontrollers. Designed to communicate over a Wi-Fi mesh network, each lantern can dynamically respond to control signals, creating a synchronized and interactive light show. Leveraging FreeRTOS, each node runs independently yet cooperatively in a decentralized architecture, ensuring responsiveness and reliability.

Bluetooth connectivity allows users to pair with the lanterns using a smartphone and send custom Morse code messages. These messages are parsed and translated into unique light blinking sequences, combining artistic expression with technical sophistication.

• Bluetooth Pairing: Secure BLE pairing with smartphones for local configuration and control.
• Morse Code Interpreter: User-submitted Morse code via a serial connection is interpreted into LED blink sequences.
• Custom Light Patterns: Dynamic lighting effects driven by user input, creating a personalized ambient experience
• Wireless Control: No wired connections needed for operation or interaction – fully wireless design.
• OTA Ready (Optional): Capable of supporting over-the-air firmware updates for future scalability and remote maintenance.
• Decorative Form Factor: Aesthetic lotus flower-inspired casing makes the device ideal for use in indoor or outdoor settings.
