好的,以下是实现上述要求的Arduino代码:
```
#include <IRremote.h>
#include <Adafruit_NeoPixel.h>
#define PIN 6
#define NUM_LEDS 60
Adafruit_NeoPixel strip(NUM_LEDS, PIN, NEO_GRB + NEO_KHZ800);
IRrecv irrecv(11);
decode_results results;
int white_brightness = 255;
int white_flicker = 0;
void setup() {
strip.begin();
strip.show(); // 初始化灯带
irrecv.enableIRIn(); // 初始化红外接收器
}
void loop() {
if (irrecv.decode(&results)) {
switch (results.value) {
case 0xFFC23D:
white_brightness = 255;
white_flicker = 0;
break;
case 0xFF22DD:
white_brightness = 200;
white_flicker = 0;
break;
case 0xFF02FD:
white_brightness = 150;
white_flicker = 0;
break;
case 0xFFE01F:
white_brightness = 255;
white_flicker = 10;
break;
case 0xFFA857:
white_brightness = 200;
white_flicker = 10;
break;
case 0xFF906F:
white_brightness = 150;
white_flicker = 10;
break;
case 0xFF9867:
white_brightness = 255;
white_flicker = 50;
break;
case 0xFFB04F:
white_brightness = 200;
white_flicker = 50;
break;
case 0xFF6897:
white_brightness = 150;
white_flicker = 50;
break;
}
irrecv.resume(); // 接收下一条红外指令
}
// 改变灯带颜色和亮度
for (int i = 0; i < NUM_LEDS; i++) {
strip.setPixelColor(i, strip.Color(white_brightness, white_brightness, white_brightness));
if (white_flicker > 0) {
int flicker = random(0, white_flicker);
if (flicker == 0) {
strip.setPixelColor(i, strip.Color(0, 0, 0));
}
}
}
strip.show(); // 更新灯带状态
}
```
解释一下代码的思路:
1. 定义了灯带引脚和数量,以及红外接收器对象。
2. 在 `setup()` 函数中初始化灯带和红外接收器。
3. 在 `loop()` 函数中,不断接收红外指令,并根据指令改变灯带的颜色和亮度。
4. 在改变灯带颜色和亮度时,遍历所有 LED 灯珠,将其设置为白光,并根据当前的亮度和闪烁频率进行调整。
5. 最后更新灯带状态,使其显示出改变后的灯光效果。
注意:这段代码仅供参考,具体实现可能需要根据实际硬件和需求进行调整。
