Upgrade Jukebox lighting with Arduino & WS2812 Adresable led strip

I cleaned my Kotronic jukebox and now it’s time to give this an upgrade. I will leave all of the original electronics intact and still working but I will add the WS2812 led strip inside the bezels, top and centerpieces. these will be controlled using an Arduino to simulate the “bubbler” bezels from the original wurtzinger/rock-ola jukeboxes […]
