nothing reminds us that it’s the holiday season much more than an LED Christmas Tree submission. This certainly is not the very first of its kind, however [Jose] does offer up a new method utilizing addressable RGB LEDs.
[Jose] chose to utilize 20 WS2812B RGB LEDs, which if you haven’t seen before, are RGB LEDs with an integrated controller. Yep, that’s right, just power/ground as well as 1 data line is all that is needed to manage numerous RGB LEDs. This LED tree’s style is simple: a custom-etched PCB cut it in to the shape of a Christmas tree. The WS2812B LEDs assisted keep whatever clean, so the tree lacks any type of ‘ugly’ ornaments, except for the needed bypass cap right here as well as there. For an added bonus, the tree’s LEDs are synchronized to music produced by an Arduino through a piezo buzzer. Why is it a shield? Well, the whole tree plugs in well to a basic Arduino interface. This appears like the ideal starter job to familiarize yourself with addressable LEDs, or at least to get you heated up before building your own infinity portal.
