## Method1： ##

> 1.时序的代码写法

double dis;
    void setup() { 
      Serial.begin(9600);
      pinMode(2, OUTPUT);
      pinMode(3, INPUT);
    }
    
    void loop() { 
     
      pinMode(2, OUTPUT);
      digitalWrite(2,LOW);
      delayMicroseconds(10);
      digitalWrite(2,HIGH);
      delayMicroseconds(10);
      digitalWrite(2,LOW);
      dis = pulseIn(3,1);
      dis = dis / 57;
      Serial.print("Method1:");
      Serial.println(dis);
      delay(1000);
      }

## Method2： ##

> 2.利用库函数的写法

#include <NewPing.h>
    NewPing myNewPing(2,3);
    double dis;
    void setup() { 
      Serial.begin(9600);
      pinMode(2, OUTPUT);
      pinMode(3, INPUT);
    }
    
    void loop() { 
      dis = myNewPing.ping()/57;
      Serial.print("Method2:");
      Serial.println(dis);
      delay(1000);
    }

> Ps Method1精度优于Method2！
