-====== LED Tannenbaum ======
-===== Übersicht =====
-Es ist mal wieder Weihnachten und man ist unmotiviert zu basteln? Baue einen LED Tannenbaum, das bauen geht schnell - das programmieren dauert ewig. Perfekt (Ihr müsst ja nicht programmieren, habe ich ja für euch erledigt ;D)
-{{:projekte:arduino_projekte:img-20170110-wa00011.jpg?200|}}
-===== Material =====
-  * 12x LEDs in Bunt
-  * Arduino in irgendeiner Art
-  * Widerstände ca. 470Ohm
-  * Kabel
-  * Karton / Plexiglas
