Basically, we don’t need any additional hardware to make this project. You can check one of my previous projects here: Covid-19 Outbreak tracker device for your Country/ESP8266 based Coronavirus Tracker for your country Components Required 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. Hence, the solution I Founded here is to use the Network Time Protocol (NTP).
#Nodemcu smart timer manual#
The RTC has poor accuracy and requires manual adjustments from time to time to keep date and time-synchronized.
Actually, while surfing the internet I found some disadvantages as well.
Instead, I used the NTP client to get the current date and time through the Internet. So I tried making an Internet Clock Using NodeMCU ESP8266 and 16×2 LCD without RTC Module. But, due to lockdown, there is no availability of any RTC Module. 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. Actually, we all know that the internet time clock has a precision of 0.02 to 0.10 seconds. We will fetch the time and date from the internet using the ESP8266 controller. In this project, we will design an Internet Clock using NodeMCU ESP8266 Wifi Module. Here, NTP stands for Network Time Protocol. This simple Internet Clock using NodeMCU ESP8266 gets the current Date and Time from NTP Client. In this project, we will make an Internet Clock Using NodeMCU ESP8266 and 16×2 LCD without RTC Module.
