源代码

以下是一个基于Arduino单片机的LED彩灯控制器的例程代码，您可以根据自己的需求进行修改和优化：

#include <FastLED.h>

//定义LED灯的数量和引脚
#define LED_COUNT 8
#define DATA_PIN 6

//定义彩灯的4种花样
#define PATTERN_1 0
#define PATTERN_2 1
#define PATTERN_3 2
#define PATTERN_4 3

//定义彩灯花样变换的快慢节拍
#define MANUAL_MODE_TIME 50
#define AUTO_MODE_TIME 15000

//定义控制器的复位清零开关引脚
#define RESET_PIN 7

//定义彩灯的颜色
CRGB leds[LED_COUNT];

//定义当前彩灯花样和变换模式
int currentPattern = PATTERN_1;
int currentMode = AUTO_MODE;

//定义彩灯花样变换的计时器和标记
unsigned long patternTimer = 0;
bool patternChanged = false;

//定义彩灯花样变换的节拍标记
bool tick = false;

//初始化LED灯
void setup() {
  FastLED.addLeds<WS2812B, DATA_PIN, GRB>(leds, LED_COUNT);

}

//循环控制程序

请注意，这只是一个简单的例程，您可能需要根据自己的具体需求进行修改和优化。此外，您还需要根据自己的硬件电路和接线情况进行相应调整。
