USB powered LED christmas tree

Step 6 Wiring the Tree

Okay, so the tree is built, and now all you need to do it hook it up to the USB cable, and plug this sucker in.

First, you're going to need to get all of the green and blue LEDs in parallel. As of now, there are 8 greens in parallel (bottom ring), 3 greens and 3 blues in parallel (2nd ring), and 2 greens in parallel (3rd ring). In order to get them all into parallel, you will need to jump some wires from the anodes of each ring to the anode of the next. Note: you may want to make these connections look like a Christmas tree, as the curves normally found in drawings of Christmas trees, this is quite simple to do.

Now, you can also add more of these connections to make more of the "Christmas curves" around the tree. The light from the LEDs should color them in later, if you don't have any green wire laying around. (I used Hard Drive cable)

Next, hook a wire up to the red LEDs' anode, and snake it down to the bottom of the tree. This wire will have its own resistor.

Finally, hook up the White LED's wire, and like the previous step, snake it down to to bottom. This wire will also get it's own resistor.
