二、代碼實(shí)現(xiàn)

#include <Servo.h> const int ledPin = 8; //pin13 built-in led const int soundPin = A0; //sound sensor attach to A0 Servo myservo; void setup() {pinMode(ledPin,OUTPUT);//set ledPin as OUTPUTSerial.begin(9600); //initialize the serial communication as 9600 bpsmyservo.attach(9);//舵機(jī)引腳 }void loop() {int value = analogRead(soundPin); //read the value of sound sensor//delay(200); Serial.println(value);//print itif(value < 1000)//if the vallue of sound sensor is greater than 600{digitalWrite(ledPin,HIGH); //turn on the led//myservo.write(90);//delay(10000); //delay 200ms}else //elae {digitalWrite(ledPin,LOW); //turn off the led} }
