Thanks Jeff! I will give this a shot tomorrow. I am super excited to learn what I can do with the setup and I appreciate the help. I can already see some limitations in how I wired it though. Here’s a video when it runs correctly. The biggest drawback is that it doesn’t look random due to the symmetry of how I wired it. It would be really cool to get to a point where each gable side has it’s own spark-fire pattern running randomly.
