I just want to be able to have the computer send a command to the nodes
(which are actually firing cues in the field) to discharge electricity to
the e-match which will ignite the firework. The nodes in the field will
have a capacitor that would store electricity until it is told to release
it. I don't know what software protocol to use, that's what I need help
with as well. I've seen SNAP but I don't know if this would be a good one
or not. Any ideas?
