“The main controller in this project is the ESP8266 which is contained in the Wemos D1 Mini Module. With integrated WiFi in it, it allows many things to be done. One of them is making a clock using NTP (Network Time Protocol). NTP can be used to sync all network devices to UTC Time in a few milliseconds. By using NTP, clock making does not need an additional DS1307 module to get time data.
This clock consists of 4 digit numbers. 2 numbers represent the hour and 2 more numbers represent the minutes. The second is indicated by 2 LEDs that are between the hour and minute digits. Dispaly component to display digit numbers using 7-Segment CA.
My clock circuit is divided into two modules. First is the display module which contains display components. The second is the controller module which contains the control components”
