Transistor - NPN (P2N2222A)
This is the P2N2222A, an NPN silicon BJT (Bipolar Junction Transistor). This little transistor can help in your project by being used to help drive large loads or amplifying or switching applications. The P2N2222A is specifically rated at 40V and 600mA max.
This is the transistor used in our Sparkfun Inventor's Kits.

Interactive 3D Printed LED Diamond Prop
April 19, 2018
In this tutorial, we will learn about how to create an interactive theatrical prop for a performance by 3D printing a translucent diamond prop using a non-addressable RGB LED strip and AT42QT1011 capacitive touch sensing.
Core Skill: Electrical Prototyping
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

This is a great Transister
It is totally doped! The P is even better then the N as far as doping goes.
Hey how about a "transistors 101" tutorial? Show some examples of using transistors, and exactly what they do in several types of circuits. I think doing this with a lot of basic components, and how they interact with each other would be useful (like, say how how to make a set of blinking LEDs using capacitors, transistors, and resistors?
Done & done: SparkFun According to Pete 7-5-11: Diodes and Transistors
Pete puts out some great material in this tutorial. He's got others that are pretty informative as well.
