Sounds like a perfect test bench for a real‑time microcontroller, maybe an Arduino or ESP32, with a high‑frequency timer interrupt reading the foot‑pressure sensors and updating the LED array. The trick is to keep the debounce low and the ISR quick—any delay over a few microseconds will throw off the shuffle rhythm. You could run a simple phase‑locked loop to sync the dance pattern to the beat; just make sure the output phase is quantized to the panel matrix so the lights don’t jitter. If you over‑engineer it, you’ll end up with a laser‑sharp groove, but a little sloppy glitching can add that human feel. Give it a shot and watch the panels dance—just remember to keep the power rail clean, or you’ll get a flicker that looks like a bad USB cable.
