Description

Smart Clock

This project is a Wi-Fi-enabled digital clock built around an ESP32 module that drives a four-digit MAX7219 7-segment display to show real-time hours, minutes, and seconds. A responsive web interface, served by the microcontroller, allows you to set the time, alarms, countdowns, timezone, and home-network credentials. Meanwhile, a buzzer and physical button provide audible alerts and quick dismissal. Running in dual AP/STA mode, the clock creates its own setup hotspot, reconnects to your home Wi-Fi for hourly SNTP synchronization, and stores all settings in NVS for stand-alone, always-accurate operation.
