This project uses an ESP32-C3 and a MAX7219-based LED Matrix display (via the MD_Parola library) to display scrolling text.
A captive portal-style web interface is hosted on the ESP32, allowing users to update the displayed text and scrolling speed from any Wi-Fi device.
- 📶 ESP32-C3 runs in Access Point mode (no external Wi-Fi needed).
- 🖥️ Captive web interface with a modern responsive UI.
- 🔤 Update the display text dynamically.
- ⏱️ Control the scrolling speed (10–500 ms).
- 🎨 Stylish, mobile-friendly HTML/CSS with subtle animations.
- ⚡ Real-time updates via
/setTextendpoint.
