“我用一个以太网插板负载到Arduino上。如此我便实现了打开我的车库门……就是这样! 我也安装了一个磁传感器,门是开着的或者封闭的都可以让我知道。所有都通过Telnet实现。 我修改了来自聊天服务器代码。现在贴出代码给爱好者使用。“   图一  安装在车库里的Arduino装置 图二 正在打开车库门 图三 用手机远程控制车库门开关 代码： #include SPI.h #include Ethernet.h String readString; // Enter a MAC address and IP address for your controller below. // The IP address will be dependent on your local network. // gateway and subnet are optional: byte mac[] = {   0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; IPAddress ip(192,168,1, 177); IPAddress gateway(192,168,1, 1); IPAddress subnet(255, 255, 0, 0); // telnet defaults to port 23 EthernetServer server(23); boolean alreadyConnected = false; // whether or not the client was connected previously const int analogInPin = A4; int relay = 3; int sensorValue = 0; void setup() {     pinMode(2, INPUT_PULLUP);   pinMode(relay, OUTPUT);     digitalWrite(relay, HIGH);   // initialize the ethernet device   Ethernet.begin(mac, ip, gateway, subnet);   // start listening for clients   server.begin();  // Open serial communications and wait for port to open:   Serial.begin(9600);    while (!Serial) {     ; // wait for serial port to connect.
