How to Set Up a Real-Time Clock (RTC) with ESP32 and DS3231 Using NTP Time Synchronization

Introduction Accurate timekeeping is crucial for electronics and IoT projects. A Real-Time Clock (RTC) is essential for maintaining precise time, especially during power outages. However, more than relying solely on the RTC module might be required for long-term projects due to drift over time. This is where Network Time Protocol (NTP) comes in. By synchronizing the RTC with an internet time server, you can ensure that your system stays perfectly in sync, regardless of how long it runs. In this guide, we’ll show you how to set up a Real-Time…

world corona real time counter

Novel coronavirus (Covid-19) is declared a pandemic by WHO. Almost all country is suffering and most of them are in a lockdown situation. Hundreds of thousands are infected and thousands are dead and this number is increasing exponentially. Only emergency services like hospitals, electricity, water supply are in operation with possible precautions. People are not allowed to step out of their homes. Some websites like Worldometers, Corona Virus Esri API show real-time corona cases, the number of recovers, deaths, etc. Based on the data displayed over this website we will…

author prototype of rtc and NTP clock

In the tutorial Arduino NTP Clock using NodeMCU and DS3231, you will learn to make an accurate clock using the RTC module and NTP server. This circuit automatically updates the time of the RTC module from the network time protocol server. RTC module shows some time delay after some days/week, this is due to temperatures dependent oscillator used in this module. The external oscillator is more prone to temperature than an internal oscillator. DS3231 module has an internal oscillator that is less prone to temperature and humidity but still has…

A small, cheap, reliable device is making its way into technology. We call it the ESP8266 Wi-Fi module which has reached almost everywhere. However, the fact that its related information on datasheets and documents are provided in the Chinese language; Mandarin makes the implementation process complicated. As a solution, people have opted for the ESP8266 community forum which discusses issues users of this module tackle while programming this module. This small wifi-chip ESP8266 constitutes a built-in 32-bit low-power CPU. The chip itself can be employed as a stand-alone device or…
