Pixel Pushers are these devices that you can plug Ethernet and LED strips into.
You can send UDP packets to the devices over Ethernet to tell them to set the colors of the LED strips.
The normal way to drive these is through something called Processing, a Java-like environment that includes a Pixel Pusher plugin.
If you would rather use OCaml to drive them, this library is for you!
opam install pixel_pusher
Add pixel_pusher to your dune config libraries stanza.
You can look at the https://github.com/mbacarella/kindredspirit/ project for an example of real-world usage.
