Introduction: Arduino Network Time Clock
When pressing the button, the system connects to the local wifi and retrieves the current date and time from a remote network time server via NTP. The data will be shown on the display for about 10 seconds. After that, the system shuts down itself via soft off pin of the button. And then, the button can be pressed again.
