【项目设计】
使用自发电无线开关,控制变换灯环炫彩效果。
【硬件】
主板使用Arduino,灯环为93灯/6环 WS2812B RGB 圆环灯。

【fastled库】
FastLED 是一款功能强大,简单易用的控制WS2812, LPD8806, 等LED光带的Arduino第三方库。 目前FastLED是公认的Arduino开发者应用最为广泛的LED控制库之一。下载地址:https://github.com/FastLED/FastLED/releases
【库安装】
使用“加载库”,加载库文件“FastLED-3.5.0.zip”。

【测试】
1、点亮一个灯,灯环接12引脚。
  1. #include <FastLED.h>
  2. #define NUM_LEDS 1
  3. #define DATA_PIN 12
  4. #define CLOCK_PIN 13
  5. CRGB leds[NUM_LEDS];
  6. void setup() {
  7.     FastLED.addLeds<NEOPIXEL, DATA_PIN>(leds, NUM_LEDS);  // GRB ordering is assumed
  8. }
  9. void loop() {
  10.   leds[0] = CRGB::Red;
  11.   FastLED.show();
  12.   delay(500);
  13.   leds[0] = CRGB::Black;
  14.   FastLED.show();
  15.   delay(500);
  16. }
复制代码
2、同时点亮两个灯环,两灯环分别接12,11引脚。
  1. #define DATA_PIN1    12
  2. #define DATA_PIN2    11
  3. void setup() {
  4.   FastLED.addLeds<LED_TYPE,DATA_PIN1,COLOR_ORDER>(leds, NUM_LEDS).setCorrection(TypicalLEDStrip);
  5.   FastLED.addLeds<LED_TYPE,DATA_PIN2,COLOR_ORDER>(leds, NUM_LEDS).setCorrection(TypicalLEDStrip);
  6. }
