工具：

硬件：arduino开发板，麦克风模块和若干杜邦线

声音拾取模块：

LD3320语音识别模块程序流程图 ld3320语音识别arduino程序_引脚

接线：

麦克风模块的A0引脚接arduino开发板的A0引脚

步骤：

一、打开arduino软件

二、使用以下程序：

<实验1> 判断模块的好坏

volatile int item;

void setup(){
  item = 0;
  Serial.begin(9600);
  pinMode(11, OUTPUT);
}

void loop(){
  item = analogRead(A0);
  Serial.println(item);
  if (item >= 70) {
    digitalWrite(11,HIGH);

  } else {
    digitalWrite(11,LOW);

  }

}

此时串口监视器会显示当前声音的模拟量，可根据模拟量的阈值范围添加响应的内容

程序：

现象：加入了热释电红外检测，红外和声音检测到人亮不同颜色的灯，同时OLED屏显示
