DIY Big Digital Clock

This week project is a big digital clock, I left the used code below in case anyone finds it useful.

Enjoy!!

The STL files in case anyone feels like doing one:

Udp NTP Client

Get the time from a Network Time Protocol (NTP) time server
Demonstrates use of UDP sendPacket and ReceivePacket
For more on NTP time servers and the messages needed to communicate with them,
