ESP32 POV Display

This project implements a rotating Persistence of Vision (POV) display using an ESP32 microcontroller. The display creates images in the air by rapidly spinning and lighting up APA102 LED strips in sync with a hall sensor.

🔧 Hardware

• ESP32 DevKit v1
• 2x APA102 LED strips
• Hall sensor for rotation synchronization
• 3D-printed or custom-built rotating structure
• Power source
• LittleFS for image storage or live UDP image streaming
