随着城市化进程的加速及人们经济生活水平的提高，汽车工业的发展，我国城市轿车购买力逐渐增强。以致于大中城市私人汽车数量的激增,那么作为新一代车族，每一个人都梦想拥有自己的车库，而车库的笨重及不方便性，甚至现在某些自动门的价格过高，使很多人望而却步，为了实现每个爱车人的高自动化车库的梦想，我们基于ARDUINO平台设计了自动车库门系统，并添加了警报模式，实现了一种系统，两种模式，使你的车库不再怕被“骚扰”。
使用模块
超声波模块*1
红外线遥控器*1
蜂鸣器*1（也可以自行加警报灯）
舵机*1（发电机也可）
LCD显示屏
面包板*2
Uno开发板*3
模块工作原理
本系统核心模块时超声波测距，通过测定不同距离，以及红外遥控对不同模块的切换，实现车库门的自动开关以及无人情况下的报警。同时人性化加入显示屏实时测距，以及减少误报警的影响。
这里展示较难模块的连接方式（需要自行组装）。
下面是实物的展示：
然后把代码录进各自的开发板，代码如下：

// Dumps out the decode_results structure.
// Call this after IRrecv::decode()
// void * to work around compiler issue

液晶屏
#include <LiquidCrystal.h> //调用arduino自带的LiquidCrystal库
LiquidCrystal lcd(12, 11, 7, 6, 5, 4);
int cm;
const int TrigPin = 2;
const int EchoPin = 3;
void setup()
{Serial.begin(9600);
pinMode(TrigPin, OUTPUT);
pinMode(EchoPin, INPUT);
lcd.begin(16, 2); //初始化LCD
lcd.print("2016 1 12 tuesday"); //使屏幕显示文字
delay(1000); //延时1000ms
}
void loop ()
{
int val;
digitalWrite(TrigPin, LOW); //低高低电平发一个短时间脉冲去TrigPin
delayMicroseconds(2);
digitalWrite(TrigPin, HIGH);
delayMicroseconds(10);
digitalWrite(TrigPin, LOW);
cm = pulseIn(EchoPin, HIGH) / 58.0; //将回波时间换算成cm
cm = (int(cm * 100.0)) / 100.0; //保留两位小数
Serial.print(cm);
Serial.println("cm1");
delay(1000);
val=(cm%1);
lcd.clear(); //清屏
lcd.print(" 1 12 Tuesday"); //使屏幕显示文字
lcd.setCursor(0, 1) ; //设置光标位置为第二行第一个位置
lcd.print("dis ");
lcd.print(cm);
lcd.print("cm");
delay(500);
}
现在一个完整的车库系统就做好了，当然我们是新手，也希望大家多多指教。
