首先我们要准备些啥子呢? 1.一个超声波传感器。 2.一个便宜的几块钱的舵机。 3。一个arduino的板,什么板都行。为了接下来的吹牛逼,我使用了MEGA. 4212

























首先我们要准备些啥子呢?

  • 一个超声波传感器。
  • 一个便宜的几块钱的舵机。








  • 一个arduino的板,什么板都行。为了接下来的吹牛逼,我使用了MEGA.


4212








  • 面包板
     
面包板picture没了,刚才肚子饿了。就,,,,,,,,


  • 首先我们要把这里面的配角舵机和超声波传感器缝上,胶上,钉上。都行。你说用口水。啊,你以为是502啊。
  • 然后我们根据基本法连线。

























  • 只要按照基本法你最后的连线肯定是这幅鬼样子的。
     












  • 万里长征最后一步就是,,,,,等等,我要出个示意图。

打通他们的任督二脉就行。

arduino代码:

#include <Servo.h>. 
const int trigPin = 10;
const int echoPin = 11;
long duration;
int distance;
Servo myServo; // Creates a servo object for controlling the servo motor
void setup() {
  pinMode(trigPin, OUTPUT);
  pinMode(echoPin, INPUT);
  Serial.begin(9600);
  myServo.attach(12);
}
void loop() {
  for(int i=15;i<=165;i++){  
  myServo.write(i);
  delay(30);
  distance = calculateDistance();
  Serial.print(i);
  Serial.print(",");
  Serial.print(distance);
  Serial.print(".");
  }
  for(int i=165;i>15;i--){  
  myServo.write(i);
  delay(30);
  distance = calculateDistance();
  Serial.print(i);
  Serial.print(",");
  Serial.print(distance);
  Serial.print(".");
  }
}
int calculateDistance(){ 
  
  digitalWrite(trigPin, LOW); 
  delayMicroseconds(2);
  digitalWrite(trigPin, HIGH); 
  delayMicroseconds(10);
  digitalWrite(trigPin, LOW);
  duration = pulseIn(echoPin, HIGH);
  distance= duration*0.034/2;
  return distance;

请各位放心,这些代码本人亲自体验过,编译过。实现过。
