Network Clock using ESP8266 and OLED display
https://www.electronics-lab.com/network-clock-using-esp8266-oled-display/
There are several situations where using an RTC could adversely affect your project by increasing cost, size, time accuracy or IO requirements. To prevent this, especially in ESP/WiFi-based or other clock-reliant projects, makers usually turn to obtain time information from NTP servers. I recently came across a project by BitsandBlobs which used standalone NTP Servers […]
