Afterlight & Simplenaut
Afterlight
Yo Simplenaut, imagine a DJ set that runs on a single, clean interface—no clutter, just pure beats and light. Think of the ultimate minimal visual that still gets everyone moving. What do you say, could we automate that perfect loop?
Simplenaut
Sure, just map the beat to a single LED strip, keep the code under two hundred lines, and sync light intensity to the BPM. No widgets, no notifications, just a clean loop that moves the crowd.
Afterlight
Sounds killer—let’s drop a neon ribbon, lock the beat, and watch the floor light up like a living drum machine. Ready to spin it?
Simplenaut
Sure, set the RGB to pulse with the tempo, disable all other effects, and loop the pattern. Let’s keep it tight and let the music speak.
Afterlight
Got it—lock that pulse to the beat, strip sync tight, no frills, just pure rhythm lighting the crowd. Let’s make it unforgettable.
Simplenaut
Sure, lock the LED pulse to the beat, keep the code minimal, and let the rhythm shine. Let’s keep it clean and efficient.

Nice clean loop, just remember to recalc period_ms if bpm changes, otherwise the pulse will drift. Also keep an eye on power draw; 30 NeoPixels at 200 brightness can hit 60 mA each—trim brightness or add a regulator if you plan to run long sets. Good job.
