An LED Effect for Every Occasion

Quality software development examples can be hard to come by. Sure, it’s easy to pop over to Google and find a <code> block with all the right keywords, but having everything correctly explained can be hit or miss. And the more niche the subject, the thinner the forum posts get. Bucking the downward trend [HansLuijten] provides an astoundingly thorough set of LED strip patterns in his comprehensive post titled Arduino LED strip effects.

Don’t let the unassuming title lead you astray from the content, because what’s on offer goes beyond your average beginner tutorial on how to setup a strand of NeoPixels. [HansLuijten] is thorough to a fault; providing examples for everything from simple single color fades and classic Cylon eyes to effects that look like meteors falling from the sky. Seriously! Check out the video after the break. Those chasing lights you see around theater signs? Check. Color twinkle and sparkle? Check. Color wipes and rainbow fades? Check, and check.

At this point, an average forum post would be a jumbled mess of source which only works on an authentic Arduino Duemilanove running at 3.3v sitting on top of the 2nd printing of the author’s favorite issue of Make. But not here! These samples work with Adafruit’s easy to use NeoPixel library as well as FastLED, the quickest pixel in the West. On top of that the examples are clear and concise and explanation is plentiful. But the best part is definitely that each effect has a video clearly showing what it looks like.

If only everything were this easy to use, the open source revolution would already be here.
