ESP32 Runway Approach Lighting Desktop Ornament This project presents a desktop intelligent ornament that provides a highly faithful reproduction of a civil aviation runway approach lighting system. It integrates an ESP32 microcontroller with hard-wired sequential logic circuitry (NE556 + CD4017) to deliver realistic visual effects, while simultaneously enabling real-time retrieval and display of METAR and TAF meteorological reports for airports worldwide. 1. Abstract This project aims to design and implement an aviation-themed ornament that combines both decorative and functional characteristics. On the hardware side, a two-layer stacked PCB structure is employed, where an NE556 dual timer and a CD4017 counter jointly realize a hybrid drive for 20 chaser ...
