The electricity does not care if you carefully measured a short wire or used a reasonably long wire. Use whatever style you like! There are 4 pins, where pin 1 is the shortest and located on the side with the flat edge.

You will need to spread the pins slightly so they fit into 4 separate groups of holes. Pin 2 needs to be connected to ground, so place a short wire between that hole group and the ground row.

On each of the 3 positive pins, place a ohm resistor red, red, brown, gold. Unlike a light bulb, the diode inside a LED will use as much power as it can. You must connect a resistor which will serve to limit the power. Never connect a LED directly to the power supply. Doing so would destroy the LED.

Now you are ready to test if the LED works. It is always good to test your connections if possible before you attempt to make them work from code in the Arduino software. The LED should light! Repeat this test for the Blue and Red. Remember, do not touch the power directly to the LED. A resistor must always be connected between the power and LED.

There are many pins to choose from! You should pick 3 pins with the PWM feature. Here are the Teensy pinout diagrams and the old Teensy 1.

Introducing the WS2812B LED Strip

Using the Teensy 2. Just plug in 3 wires to connect from the resistors to the pins. Connect the base through a 1k resistor to the Arduino output, the collector to Vcc, and the emiter through the LED and then a ohm 1-watt resistor to ground. Don't forget you'll need something that can handle the 9 watts for the LEDs, and don't use the on-board Vcc and Gnd pins for the transistors collectors and emiters, that's a lot of current for the tiny traces on the board.

Just because my current knowledge is limited does not mean I'm unwilling to learn. But gee, thanks for the confidence. Word, I hear you.

Just hard to know where to start when there are so many ways to execute a simple project. What I want to do is create 6 box lamps, each illuminated by some sort of light source. The boxes are quite large, so because the high power LEDs are out of the question I imagine I'd use multiple ordinary ones. I'd also like to have control over each of these box lamps color, blinking, etc individually.

I was immediately drawn to BlinkM due to my overall lack of experience and its easily programmable light sequencing, but it's quite out of my price range. Unfortunately its starting to look more and more like I'll have to fork over the cash to get this project done in time. You could try a circuit like this: That will depend on what you pick for Q2. You will need one of these circuits for each color on each LED.
