These are bare addressable 5 meter long 5V RGB LED strips that come packed with 60 WS2812s per meter. As these are bare LED strips that have no protective coating, your project won't be water proof but there is access to each WS2812 LED and each strip length can be easily modified. You will be able to control each LED RGB individually giving you the ability to create cool lighting effects for your car or perhaps under cabinet lighting in your kitchen!
Note: These come in 5m segments on a reel. They are preterminated with 0.1" spaced 3-pin connectors as well as a 2 wire power connector, as shown in the pictures.
If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

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.

Very Bright at Maximum Brightness. Requires about 5v@20A~100Watts to drive the strip. Make sure you have a capable power supply. The strip will fade to red (low power) if you power it from only one side. You will have to run power from both sides or to multiple points along the length due to resistance. The logic level ground is critical. Especially at 3.3v. Make sure you run a common ground between the LED power supply and the Logic board you are using to drive the color data. The two best libraries available for driving these strips are the Adafruit NeoPixel library and the FastLED Library.
I was shipped the GRB variant by mistake, and had to do some minor tweaks to my code to compensate. Normally, I'd dock a star for that, but I'll give a pass because of how robustly designed the strip is. I accidentally connected it backwards (5V to GND and vice versa). My power supply was shot of course, but the strip is still in perfect working condition. Sure, a couple unnecessary lines of code may be annoying, but not nearly as annoying as having to replace a $100 purchase.
