up_n_down sketch builds and uploads, but doesn't work
I have successfully build and loaded most of the other sample hexbright sketches, but no luck with up_n_down.
Arduino compiles the sketch and uploads it, but the only thing that happens is that pressing the button turns it red, but the flashlight doesn't turn on.
Am I missing something obvious? Anyone have an idea what the issue might be?
Is this a good question?
