自发电无线开关(三)炫彩灯环开关
本帖最后由 云天 于 2022-10-2 19:52 编辑【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。
#include <FastLED.h>
#define NUM_LEDS 1
#define DATA_PIN 12
#define CLOCK_PIN 13
CRGB leds;
void setup() {
FastLED.addLeds<NEOPIXEL, DATA_PIN>(leds, NUM_LEDS);// GRB ordering is assumed
}
void loop() {
leds = CRGB::Red;
FastLED.show();
delay(500);
leds = CRGB::Black;
FastLED.show();
delay(500);
}2、同时点亮两个灯环，两灯环分别接12，11引脚。
#define DATA_PIN1 12
#define DATA_PIN2 11
void setup() {
FastLED.addLeds<LED_TYPE,DATA_PIN1,COLOR_ORDER>(leds, NUM_LEDS).setCorrection(TypicalLEDStrip);
FastLED.addLeds<LED_TYPE,DATA_PIN2,COLOR_ORDER>(leds, NUM_LEDS).setCorrection(TypicalLEDStrip);
