Aurora 12 bar is a simple, straight line RGB LED sequencer/chaser. Aurora 12 bar’s hardware is almost identical to Aurora mini 18. In fact only difference are (besides their shapes) the number of LEDs and the microcontroller that they use. Oh, and Aurora 12 bar doesn’t use a single SMT (surface mount technology) part!
In addition to all the animations that other Aurora’s can do, Aurora 12 bar also has the analog input ready. By hooking up to Audio Interface, you can turn Aurora 12 bar into a full-color sound/VU meter!
Aurora 12 bar is made with 100% through-hole parts. No surface mount parts!
