In years past, I've used a timer to turn my Tune-To sign on/off, but the timer quickly drifts, so the sign typically goes on well before the show starts and turns off before the show ends. Last year, I hacked in an Arduino and a couple of SSR's with some simple C# serial port control code and was able to time it exactly to when my show starts/ends. Since that was a hack job, I decided to pull out a Boardunio and make it a little more permanent. This not only controls when my Tune-To sign turns on/off, but also my security lights after the show is over.
