I'm surprised that nobody has been asking questions about this yet. I just put mine together, it went together great and works great. I love it!
I have two quick questions-
You're supposed to be able to press and hold the "night" button to put it to sleep. That doesn't seem to work for me. I press and hold it, and the lights go off, but when I let go they come back on, on the same night. Am I doing it right?
The original mini menorah had a "demo" mode. I see demo mode mentioned in the code, but the comment // If button is pressed at turn-on, enable "demo mode" doesn't seem to lead anywhere. How do I do this?
