Here they are…

IMG_0001smAfter my little update post yesterday, the WS2812B LEDs decided to show up today. Despite taking longer than other packages from China usually do, I will say it was packaged well. It came in a properly-sized envelope and the LEDs themselves were in an antistatic bag (the first I’ve seen from any Chinese eBay seller) wrapped with bubble wrap. I’m impressed because I usually see things come from China in the smallest possible envelopes with things wrapped in plastic wrap. Anyways, let’s take a look at the LEDs themselves.IMG_0002smThese modules are a lot smaller than I was expecting (I’ve never used WS2812B LEDs before). I found them kind of tricky to solder cleanly.

Yesterday after I made that post, I started designing a single LED module similar to these but they have through hole pads to make the wire connections or add headers. After struggling to make solder connections on these look good, I’m still inclined on doing my own WS2812B boards to make it more convenient to solder a chain of them together.

To be fair, though, a smaller gauge wire may have helped here.

IMG_0003smI was up and running minutes after soldering them together, thanks to Adafruit’s NeoPixel library and the newest Arduino IDE that makes it so easy to install through the library manager. These LEDs are very bright and they produce colors that look better than the “dumb” RGB LEDs I’ve been using so far with the Light Show and other projects. I’m sold on going forward with these LEDs in my projects, even with the higher cost. I’ll need to familiarize myself with the library more before I can actually start adding them into projects.
