How to make an IoT Digital Clock

Admin - Soup Creations April 24, 2023


Keeping track of time is essential in our daily lives, and clocks have been used for centuries to help us do just that. With the advancements in technology, we have seen the rise of digital clocks that offer more precise timekeeping and additional features such as alarm settings, countdown timers, and more. In this project, we will be building an IoT Digital Clock that is connected to the internet and can sync with an NTP (Network Time Protocol) server to provide accurate timekeeping.
