Bluetooth Audio System with ESP32 and LVGL Interface

# Bluetooth Audio System with ESP32 and LVGL Interface

## Project Description
This project was born from the idea of repurposing old PC speakers and turning them into a modern Bluetooth audio system. Powered by an ESP32, it features a custom graphical interface using the LVGL library, UART connected. The system is modular, energy-efficient, and designed for DIY enthusiasts who want to breathe new life into vintage hardware while enjoying high-quality audio. Compact and highly customizable, this project showcases the potential of combining modern electronics with upcycled components. **Hot glue** was used to secure the parts, ensuring a quick and sturdy assembly.

## Required Hardware
- **ESP32-WROOM** or similar microcontroller
- **ESP32 CYD (Cheap Yellow Display)** for display and touch interface (running **MicroPython**)
- Old PC speakers
- Audio amplifier module for the ESP32 (e.g., **UDA1334a**)
- Power supply, preferably **12V**
- **Buck converter** to step down the vol
