I'm a retired aerospace engineer and have been in electronics my entire life. I've built many Christmas decorations and parade float systems using LOR boards and Arduino's for custom control of different systems, but when I found this site, it was obvious that I am behind the power curve when it comes to Christmas light controls. You guys are really state-of-the-art when it comes to this. I'm also just amazed at all the work the members of this board have done to help others with this hobby. Although I'm new, I've already learned a bunch from you guys and appreciate all your input. Thank you. I'm sure I'll be spending lots of time here.
