I needed a twinkling starry sky for the sets of the Christmas play. This code is very good for that purpose. Thanks a lot.

Hello, Thanks for your video. This works great for a project of mine, but I have one question. I see in your video that your LEDs puslate sepately from each other, while mine pulsate the same. Do you know why?
