esp32 控制ws2812灯带

采用的arduino控制，利用别人写好的模块进行控制
vs code搜索Adafruit_NeoPixel导入项目中
代码实现


#include <Adafruit_NeoPixel.h>
#ifdef __AVR__#include <avr/power.h>
#endif#define PIN 23// Parameter 1 = number of pixels in strip
// Parameter 2 = Arduino pin number (most are valid)
// Parameter 3 = pixel type flags, add together as needed:
//   NEO_KHZ800  800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)
//   NEO_KHZ400  400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)
//   NEO_GRB     Pixels are wired for GRB bitstream (most NeoPixel products)

灯带连接控制io和gnd，我的控制io插在了23上面
效果来回流星转动，还有其他效果没有调用，代码里面有，可以控制移动时间，总体数量，亮度等参数。
