Answer :

I’m no electrical engineer, and most of the items in the Instructable are foreign to me – I know the terms but not “the things” themselves – but I understand some basic concepts. Have you checked all of your soldering? Have you checked for continuity in all of your circuits? Have you checked the integrity / continuity / “aliveness” of all of your components? Is the battery installed with the correct polarity? (That was one part of the written instruction that I didn’t get at all: which way is “up” for the battery?)
