WS2812B LED Strip Addressable Programmable 30LED/M 3.2FT 1M, Cuttable Consistant Color for Display Screen, DC 5V Non Waterproof WS2811-Chip Built-in …

I used a small 2 amp, 5V wall-to-DC power supply to power the strip and a separate 9V power supply for my arduino uno. In Arduino IDE, if you go to sketch -> Include Library -> Manage Libraries, you can search for Adafruit Neopixel, which is the library you need. Once you've installed this library, go to file -> examples -> (scroll down) Adafruit Neopixel -> strandtest. By default the parameter that defines the number of LEDs in the strip is set to 60, so change it to 30 if you are using this specific strip. Wire everything up per the instructions on the packaging, upload the strandest code into your arduino, and boom! The LEDs should start putting on a fabulous display. I haven't messed around with making a custom lighting pattern or anything but from what I've seen so far, if you have any experience at all with programming Arduino it shouldn't be too difficult as the Adafruit Neopixel library seems pretty intuitive.As far as the performance of the strip itself, I have no complaints whatsoever. The LEDs are super bright and the colors are impressive.

I got a few of these for my high school electronics class. You need a microcontroller (I use Arduino clones), USB cable, programming software (I use the Arduino IDE), and a resistor. I used a 470 ohm resistor, and this should be placed in series with the Signal line. I chose this short run of NeoPixels so that I would not need to buy a separate power supply. I actually cut the strips into 3 pieces of 10 LEDs each. If you make all 10 the brightest white you can overstress the USB power supply or the microcontroller, otherwise you should be okay with just 10 LEDs. I always set the brightness in software to about 1/5 max to avoid any current supply problems. Is you use the USB power from a PC, that should be clean enough to not require a capacitor. If you're using one of those switching power supplies that you plug in to the wall, you will need a capacitor.Sample code can be found online. You can use either the FastLED library (on github) or Adafruit's NeoPixel library. There could be a learning curve there too if you have not used external libraries before.So far they work for me. I have not tested the adhesion. I have had other LED strip lights not stick, so I am prepared to use a bead of hot glue or some other kludge.

No problem getting this working with arduino neopixel library. Used a 470 Ohm resister on the signal wire from the arduino, and a 1000uF cap on the power source to tame it. Beautiful rich colors. Parts of the sticker label lifting (haven't stuck it anything yet), but that's ok. Minimal instructions on/in the package, but the adafruit neopixel web pages give you the information you need. Next step I'll try to get these working with raspberry pi.

The Green channel on one of the LEDs is broken. I can work around it, but it's still disappointing.
