Tiny NTP Server with Esp32

An ESP-IDF project for ESP32 that joins Wi-Fi, syncs time via SNTP (immediate mode), then displays a clean 12-hour clock: single-line UART with seconds and a TM1637 4-digit HH:MM with a blinking colon. Includes a minimal TM1637 driver, configurable pins/servers, and defaults to Asia/Kolkata (IST).
