I am about to use the neopixel rings to light a large garden pond. I can think of two ways to do this,
1) I can make each neopixel self sufficient with it's own trinket, and run two wires between them to sync. I do have a few operations that I want synced up. But most of the time they operate independently
2) Run one UNO with all of the lights hung off. But I think I would end up making 4 separate loops. Daisy chaining them would require a lot of wire running around
Any thoughts on best (or a better) approach.
Thanks

Re: Multiple Neopixel Rings
Distributed control with Trinkets sounds like a better approach. You can run into problems if the signal wires between pixels get too long.

Re: Multiple Neopixel Rings
If for no reason other than power distribution you want to limit the number of rings in a group, so maybe one trinket per group. A kind of hybrid approach that lets you balance power, data, program complexity and cost. I don't know how you intend to synch them but each Trinket can spit out data on a different port than it's receiving, minimizing the length of signal wires. You could pass data between them using a scheme similar to the way NeoPixels talk to each other. Each one strips off part of the input data and passes the rest on to the next.
