The Ruiz family did some last minute pumpkin carving yesterday and had the opportunity to light up the Jack-O’-Lantern with some NeoPixels. But in stead of pulling out the soldering iron, wires, micro-controller and a NeoPixel strip, we only used a single Circuit Playground board. Using PhilB’s code, the 10 on-board NeoPixels emit a lovely candle flicker effect, which looks both organic and authentic. It’s being powered by a 2500mAh lipo battery. To keep the components from getting messy, we placed them in a sandwich bag which should keep them nice and dry.
Although there are much cheaper methods of lighting, this project provides a much brighter result. The simulated candle sketch is a great example of optimized code and teaches you how to create light using math… and when Halloween is over, the Circuit Playground can be used in many other projects :-).
