... that's such a cool thing to happen! The experience of a skeleton reaching out of the screen and terrifying you in real-life. I love it!
The setup process is something I always fear will diminish enthusiasm, so we definitely worked hard to make this process as smooth as possible. Hopefully it'll be streamlined even more in the near future, though I'm definitely excited to hear that it was smooth for you.
Ahh, awesome point, I'll change the room numbering!
cloudBit disconnection from the usb power module was a big fear of mine, though attaching a wire in-between is an awesome idea. Something I've found helpful too is to put shoes on the cloudBit so it doesn't disconnect from power. That sounds like something that could be messaged more clearly in the getting started guide!
So, most littleBits circuits are analog, and can send and receive a range of values. There are certainly exceptions (Logic bits, Pulse, timeout, etc.), but most of our bits do send or receive analog signals. Minecraft redstone is also analog. If you connect P3 usb power -> slide dimmer -> cloudbit, and then in the game connect the receiver to redstone dust, you can actually see the dust glow brighter as the dimmer is moved to the right. However, /most/ minecraft redstone things are binary, e.g., piston, lamp, pressure plate, button, lever, TNT, etc. In fact, I think one of the only ways to use the analog nature of redstone might be to use the comparator block. I'll have to look for a good example use case, several people have asked this now.
