7-segment time + date + weather display

7-segment time + date + weather display.

Functions:

• Shows time + date + weather (temperature and humidity) for your location.
• You can choose in the settings if you want to have the temperature as Celsius or Fahrenheit value.
• All settings can be configured in the “settings.h” file in the Arduino IDE.
• You will need to add the settings for your WiFi and optional for weather information.
• Update 25.06.2023: Working on software version V2.0.0: (Currently in test status)
  • Added web interface to store the settings in the ESP32 flash instead of the code.
  • Removed the “settings.h” file, because all settings can be set in the web interface
  • Added these functions in the web interface:
    • Integration of my new WiFi Manager to store the WiFi and other initial settings in the ESP32.
    • Optional night mode with reduced or to off set led intensity during night times.
    • Brightness control via web interface.
    • Date format switch for “DDMMYYYY” or “MMDDYYYY” format.
    • During startup the from your router received IP-address is shown.
    • Restart of the clock can be done via web interface.
    • All settings can be deleted via web interface incl. the WiFi config.
    • If your router cannot be reached anymore the WiFi config gets deleted.
    • Many information values of the ESP32 are shown.
    • Your NTP time server and time zone can be set in the inter too.
    • The weather data update every 5 minutes.
• Update 27.06.2023: Software version V2.0.0 released: GitHub
• Update 07.07.2023: On intensity setting 0 the display is turned off now. See V2.1.0.
• Update 01.10.2023: Added some additional display outputs and fixed a bug. See V2.1.1.
• Update 02.12.2023: Software now supports negative temperature values. Who could think of these in summer? ;-) See V2.2.1 on GitHub.
