Internet Clock Using NodeMCU ESP8266 and 16x2 LCD without RTC Module

In this project, we will make an Internet Clock Using NodeMCU ESP8266 and 16x2 LCD without RTC Module. This simple Internet Clock using NodeMCU ESP8266 gets the current Date and Time from NTP Client. Here, NTP stands for Network Time Protocol.

 

Overview

 

In this project, we will design an Internet Clock using NodeMCU ESP8266 Wifi Module. We will fetch the time and date from the internet using the ESP8266 controller. Actually, we all know that the internet time clock has a precision of 0.02 to 0.10 seconds. While being on lockdown due to coronavirus, I spent some time browsing the internet and found an Internet Clock that is made using RTC Modules like DS1307, DS3231 or PCF8563 to get the time. But, due to lockdown, there is no availability of any RTC Module.

 

So I tried making an Internet Clock Using NodeMCU ESP8266 and 16x2 LCD without RTC Module. Instead, I used the NTP client to get the current date and time through the Internet. Actually, while surfing the internet I found some disadvantages as well. The RTC has poor accuracy and requires manual adjustments from time to time to keep date and time-synchronized.

 

Hence, the solution I Founded here is to use the Network Time Protocol (NTP). If your NodeMCU ESP8266 project has access to the Internet, you can get date and time (with precision within a few milliseconds of UTC) for FREE. Basically, we don’t need any additional hardware to make this project. You theiotprojects.com/internet-clock-using-nodemcu-esp8266-a...
