Christmas tree with Arduino

   original article

   Inspirred by Doz' Blog and article An Arduino Project: How To Make Flashy Christmas Lights Ornaments I made a Chistmas tree with 9 + 1 leds (9 in tree and one in Arduino nano board).

   Test schematic is

and real test assembly is

   I write 2 sketches, first (christmas_lights_1.ino) chose random the led for power on, wait 50ms, chose random the led for power off, second sketch (christmas_lights_1a.ino) is like first, just change time wirtting as be random from 10 to 100ms.

   I made 3 movie:

- with first sketch and all red leds - Arduino Christmas lights

- second sketch with all red leds - Arduino Christmas lights (2)

- second sketch with various leds - luminite pentru bradul de Craciun (3)
