Step 2Schematics
Okay, now that you have your materials you need to assemble your LEDs. Here is my schematic below.
You'll notice that I hooked these up in parallel. I did this because my power adapter only has a 5v output. By running the LEDs in parallel each LED gets up to 5v. The other option is to hook them up in a series, but then I would need a power source capable of providing enough current for each LED individually (say I have 5 LEDs that each require 3 v I would need a power adapter with an output of 15v).
On a side note, since I couldn't find 39 ohm resistors I just used the 47 ohm resistors for each LED.
