In this tutorial, we will learn how to get the current date and time from the NTP server with ESP32 acting as an NTP client and Arduino IDE. Accurate timekeeping is important for IoT applications and the NTP protocol provides a reliable way to synchronize the ESP32’s internal clock with a time server on the … Read more
In this tutorial, we will create two types of IoT based clocks such as Analog and Digital using OLED display and ESP32 and ESP8266 NodeMCU development boards. We will use the NTP server to acquire the current time and display it on the OLED for the digital clock in a 24-hour format consisting of HH:MM: … Read more
In this tutorial, we will learn how to get the current date and time from the NTP server with the ESP8266 NodeMCU development board and Arduino IDE. In the data logger applications, the current date and timestamp are useful to log values along with timestamps after a specific time interval. The time.h header file provides … Read more
