Complete module : xmas tree + controller pcb
+ frontWhile in the past we usually had to make do with a string of tiny, fragile light bulbs, which would flash at the most, now we can choose from many different types of LED lights with built-in light effects. But as a real electronics enthusiast you can, of course, make one that is much better and more elaborate, such as this Xmas tree which, with 56 LEDs can display an extensive light show lasting more than three-quarters of an hour.
