Hey there,
Trying to get my LEDs to blink in a nice long sequence. Like 1gig worth of ones and zeros long. I can't have my computer connected to it, either. So what is my best bet? USB or perhaps SD? What's the cheapest/easiest to recycle old stuff into? Thoughts?
Thanks,
G
The SD card is your best option for a large ammount of external storage.
Took at look at the SD lib for Arduino, seems straight forward enough. Something like this? SD Card Module for Arduino
What's the purpose of such a long blinking sequence?

Can't argue with that. 
Perhaps not, but as far as visual effect goes, I cannot see how it would be distinguishable from either pseudo-random blinking, or a sequence constructed from a series of modules (including pseudo-random) each of which could be defined in terms of a program sequence and called in turn according to a much more limited script which would fit in the normal program memory.
...I cannot see how it would be distinguishable from either pseudo-random blinking...
Unless, he as planned a specific sequence of a couple of gigs of binary data
Unfortunately I'm bound by honor to see that these bits are rightful in nature, but I appreciate your ideas.
Art is more than just visual effects these days.
It could be that the blinking light represents some data that is being visualised. Art is now about the idea behind the implementation.
