Arduino IR Candle Controller

OverviewTired of hunting for multiple candle remotes? This Arduino-based IR controller lets you turn multiple LED/flameless candles on and off with just two buttons! Perfect for creating ambient lighting setups that you can control from one central device.The Problem This SolvesMy wife has been collecting various LED lights over the years for Halloween decorations - fake candles, spooky lanterns, that kind of thing. Over time she lost the remotes one by one, as you do. I tried using other IR remotes we have lying around and sometimes the lights would flicker or react a little, but never actually turn on or off properly. It's like they were receiving something but not the right commands.The SolutionThis simple Arduino Nano-based controller sends the correct infrared signals to control all your LED candles at once. One button turns them all on, another turns them all off. No more hunting for lost remotes!What You'll GetComplete Arduino code (main controller + diagnostic code to f
