ws2812b效果研究之六 FirstLight

就是一个白色的点向上发射,为了看起来不卡顿,帧率一定要上去,最好达到100帧(也就是delay(10))

// Move a white dot along the strip of leds.  This program simply shows how to configure the leds,
// and then how to turn a single pixel white and then off, moving down the line of pixels.

// For led chips like WS2812, which have a data line, ground, and power, you just
// need to define DATA_PIN.  For led chipsets that are SPI based (four wires - data, clock,
