用Arduino uno,Apds9960和WS2812B来实现手势控制灯的亮度和颜色,其中WS2812B的数据引脚接Arduino的6接口,灯带数量为30,初始状态为白色,定义一个变量是否有中断发生也就是是否有手势,当有手势出现时,灯带为彩色,收拾出现后,根据手势判断颜色,手势向下灯带颜色为绿色,手势向上灯带颜色为黄色,手势向左灯带颜色为蓝色,手势向有灯带颜色为紫色,其中用到的库有FastLED.h,Adafruit_NeoPixel.h,SparkFun_APDS9960.h,Wire.h的程序

以下是您所描述的Arduino程序代码:
```
#include <FastLED.h>
#include <Adafruit_NeoPixel.h>
#include <SparkFun_APDS9960.h>
#include <Wire.h>
#define LED_PIN 6
#define LED_COUNT 30
CRGB leds[LED_COUNT];
Adafruit_NeoPixel strip(LED_COUNT, LED_PIN, NEO_GRB + NEO_KHZ800);
SparkFun_APDS9960 apds = SparkFun_APDS9960();
bool interrupt = false;
void setup() {
strip.begin();
strip.show();
FastLED.addLeds<WS2812B, LED_PIN, GRB>(leds, LED_COUNT);
// Initialize APDS-9960 (configure I2C and initial values)
Wire.begin();
if (apds.init()) {
Serial.println("APDS-9960 initialization complete");
} else {
Serial.println("Something went wrong during APDS-9960 init!");
}
// Start running the APDS-9960 gesture sensor engine
if (apds.enableGestureSensor(true)) {
Serial.println("Gesture sensor is now running");
} else {
Serial.println("Something went wrong during gesture sensor init!");
}
}
void loop() {
if (interrupt) {
uint8_t gesture = apds.readGesture();
switch (gesture) {
case DIR_UP:
for (int i = 0; i < LED_COUNT; i++) {
leds[i] = CRGB::Yellow;
}
FastLED.show();
break;
case DIR_DOWN:
for (int i = 0; i < LED_COUNT; i++) {
leds[i] = CRGB::Green;
}
FastLED.show();
break;
case DIR_LEFT:
for (int i = 0; i < LED_COUNT; i++) {
leds[i] = CRGB::Blue;
}
FastLED.show();
break;
case DIR_RIGHT:
for (int i = 0; i < LED_COUNT; i++) {
leds[i] = CRGB::Purple;
}
FastLED.show();
break;
default:
for (int i = 0; i < LED_COUNT; i++) {
leds[i] = CRGB::White;
}
FastLED.show();
break;
}
interrupt = false;
}
}
void handleGesture() {
interrupt = true;
}
// Attach interrupt to the gesture interrupt handler
void attachInterrupt() {
if (apds.setGestureIntEnable(true)) {
Serial.println("Gesture interrupt enabled");
} else {
Serial.println("Something went wrong during gesture interrupt setup!");
}
attachInterrupt(digitalPinToInterrupt(2), handleGesture, FALLING);
}
```
这个程序使用了三个库:FastLED.h,Adafruit_NeoPixel.h和SparkFun_APDS9960.h。以下是每个库的简要说明:
- FastLED.h:用于控制WS2812B灯带的颜色。
- Adafruit_NeoPixel.h:另一个用于控制WS2812B灯带的库。
- SparkFun_APDS9960.h:用于控制APDS9960手势传感器。
程序通过定义LED_PIN和LED_COUNT常量来指定连接到Arduino的WS2812B灯带的引脚和LED数量。 setup()函数初始化了所有必要的库,并启动APDS9960手势传感器的引擎。 loop()函数检查一个名为interrupt的布尔变量,以确定是否触发了手势传感器中断。如果是,则读取手势并根据手势指示将LED的颜色设置为相应的颜色。 handleGesture()函数与手势传感器中断连接,并在中断触发时将interrupt变量设置为true。最后, attachInterrupt()函数将handleGesture()函数连接到引脚2上的中断(FALLING)。
希望这可以帮助您开始实现手势控制WS2812B灯带的项目!
