Using these NeoPixel LEDs is a breeze. First, power the LEDs with 5VDC. Then, follow the instructions in our detailed NeoPixel Uberguide to integrate them into your project. The guide also has ready - to - go library and example code for different Arduino models. When it comes to soldering, keep in mind that these LEDs are very small and not designed for hand - soldering due to the pads being underneath. If you're not experienced with surface - mount soldering, it's best to seek professional help. For maintenance, make sure to keep the LEDs in a dry and clean environment. Avoid exposing them to extreme temperatures or moisture. If you want an easier option without soldering, you can check out our ultra - skinny half - meter - long LED strip made with these NeoPixels.
