Actually, I was doing homework yesterday....
I'll start with Ush's question: Wow you have a good memory. Yes, you are a lot different than the people I'm normally around. Honestly, I enjoy posting here...I would love it if everybody believed in the same things I believe, but then, there would be no interesting questions and discussions. I haven't picked up too many opinions because I don't post that often in the general section....All Star Wars for me 🙂
How do motion detectors work...I have no idea....some kind of sensor...which I don't know how it works. The light one probably senses a certain amout of light to shut off, when it falls below a certain amout of light, it'll turn back on....I can't expalin any further than that because I don't usually work with lights
