Updated Thunder & Lightning

Last year I posted a video showing how you could simulate a thunder storm with synchronized thunder and lightning. SEE: https://www.youtube.com/watch?v=7WtKi... This revision of that program allows you to have the sound of thunder delay for some time after the lightning is seen. This more closely simulates what happens in real life when a lightning strike might be a mile or more away. More information and the code for the Arduino are on my web page here:
