Arduino based Christmas tree

Like on any other Christma,s this year hobbyists again try to create something beautiful to make this event nice and unique. Jose have shared his project details where he builds a small Christmas tree lit with RGB LEDs.

Circuit is really simple – Arduino drives 20 RGB LEDs using WS2812b. LEDs are driven in cascade so only single data pin is required. Ornament is also equipped with buzzer. It plays along with LED effects. Great idea for Christmas gift.
