christmas tree with leds

This is my very first 3D modeling project, you will need and Arduino to drive this, you can use something like an Arduino UNO or Leonardo, schematic should be pretty easy to replicate, make sure not to drop any solder on the part, I used 3mm leds, also the code is very simple.

Materials:
8 green 3mm leds
6 red 3mm leds
220-ohm resistor
Arduino UNO/Leonardo
Cables to connect the tree to the Arduino

it's also recommended for you to have a decent soldering iron (don't go crazy a 20$ iron will do the job) leds can be had for cheap on eBay just search for "3mm leds" and you should find them no problem.
