This is a ESP8266 project that is connected to MAX7219 Dot Matrix Module to display the time and date that is fetched from the internet.

Features:

• 12/24 time format (you can select it when doing the initial setup)
• Automatic time setting (the time will be fetched from the internet)
• Auto timezone detection based on the IP location.
• Current weather display in your city (no setup needed)
• Random fun facts, will be shown every 3 minutes.

First time setup:

• Get open weather API key from here: https://openweathermap.org/api and place it in the APIKEY section in the code.
• When you turn on the clock for the first time, it will show AP mode (access point mode) on the display the first time you turn it on.
• Connect to the clock using your phone or tablet by searching for wifi network called "Wifi Clock".
• A setup page should open and you should select the wifi notwork that the clock will connect to and enter the password.
• choose the time format that you prefer.
• Setup is done...
