Here's the scenario: We have 1 arduino uno accepting DMX and converting that to a signal that is being sent out digitally (PIN 3). The digital signal then goes to several IR LED senders that control 3,200 IR, color-changing candles. I've recently added some more senders, and now some of the senders are not working (even some that were working before). I assume this is because the digital signal has been weakened due to me splitting it so many times.
I'd like to add another arduino to control half of the IR senders. I obviously already have a cable running to every device, but I know of a perfect place to "interject" the new arduino. Is this possible? Can the second arduino essentially "repeat" or decode and re-encode the digital signal? If so, what pins am I looking at and will I need any special code?
Thanks for the help!
