Put this display together so I could have a little widget on my desk showing the current COVID-19 cases in the US, but the code could easily be adapted to show whatever piece of data you think is worth having a dedicated display of such as page views or file downloads.
After starting up, the display will show "READY" and its current IP address. You then fire off the data you want it to show via UDP. This can easily be done by piping echo into netcat:
echo -n "24,116" | nc -b -w 0 -u 192.168.1.196 1337
