UPDATE: removed slightly awkward timed waits after lights flash; replaced with better flow control via "wait until" and broadcasts. Also, dimmed switches when correct combination is found (until switches reset), and added yet more comments inside. :) This is a demo project for @CobramCat in response to https://scratch.mit.edu/discuss/topic/224661/ (which seems to be proving more difficult to answer than it really needs to be – but maybe I'm missing something, in which case please clarify!) Each switch clone controls at least two of the bulb clones. Find the combination of switches to make all bulbs light up. I've included lots of comments inside, so hopefully that'll help explain what's going on. :) Yeah... it's not particularly hard! –It's just a demo of how you can make each clone control any set of other clones.
