NTP Time Synchronization with ESP32

ESP32

Overview

This project demonstrates how to synchronize time using Network Time Protocol (NTP) on ESP32 microcontrollers. By synchronizing with an NTP server, the ESP32 device can maintain accurate timekeeping, which is essential for various applications such as data logging, scheduling, and event handling.

Getting Started

  • Select ESP32DevKitC development board.
  • Install NNTPClient.h library.

Installation

  1. Clone or download this repository to your local machine.
  2. Configure the ssid and password variables in the code with your WiFi network credentials.
  3. Compile and upload the code to your ESP32 board. Alternatively, you can use the Wokwi platform for simulation.

Code Explanation

The main.cpp file consists of :

setup()

  • Connects the ESP32 to the WiFi network.
  • Sets up the NTP client and synchronizes time with the NTP server.

loop()

  • Checks if the NTP client has updated the time.
  • If the time is updated, it prints various time-related information to the serial monitor, including epoch time, formatted time, seconds, minutes, hours, and the day of the week.
