I need to know the code to program about 12 white LEDs on arduino for making them randomly twinkle or something in that nature. I'm currently working on a Disney inspired project in which I recreate one of their firework shows on a model of Sleeping Beauty Castle i made. At points in their shows, there are scattered bright LEDs on the castle that twinkle randomly and fast. I want that effect on my castle too. I also wanted to know how to program a tri color LED strip that i can use to recreate lighting in the show too. Any help is very appreciated! Thanks!!!
