clock case for 2.8" ST7789

About this design:

This is an enclosure for an alarm clock featuring an LCD screen and a rotary encoder. The base code is derived from the GitHub project Crescendo Clock . The code has been modified to work with a standard ESP32-WROOM module. The original light sensor was removed in favor of a simpler brightness control based on the time of day.Additionally, I have integrated current weather data from OpenWeatherMap.org.

What you'll need:

- ESP32 with internal WiFi antenna - 2.8” LCD (ST7789 or similar) - speaker - DFPlayer Mini MP3 player (with SD card) - standard rotary encoder - 32mm diameter knob - anti-slip foam pads - M3 self-tapping screws - M3 screws with nuts - USB-C nut-locking connector
