FAQ

• I am new to the hardware and LEDs that are needed to create a project, what's a good way to get started?

• I am running a sketch that updates the pixels quickly, but they flash or only some pixels light up

• I have connected up my Esp8266 and nothing is shown and the Pin doesn't have any output. Using the NeoEsp8266BitBangMethod works fine though.

• On my Esp8266 (or other 3.3v based Arduino) they don't show the colors correctly.

• I wish to dynamically set the number pixels, but I don't see a way to do this and other libraries expose a method to change the number of pixels like updateLength() or setPixelCount().

• How can I convert Hsl to Rgb and/or just set the colors with Hsl?

• How fast can I update my NeoPixels?

• Is there a way to specify a color using a color wheel?

• How many pixels does this library support?

• I want to have my sketch do other important work like networking; how do I use your library with other features?

• Other libraries have a method to dim all the pixels with one call. Is there a way to do this?

• On my Esp8266 when I flash the sketch the LEDs light up, is this normal?

• How do I store a reference to the NeoPixelBus in another class?

• Using DotStars, why would I use the SPI method over the general purpose method?
