Node32S กับ Arduino IDE กำหนด Port ยังไงครับ จะทดลอง forward port

  • 1 Replies
มือใหม่หัดขับ ลองเล่น Ayarafun LamLoei Node32s ตอนนี้กำหนด IP กับทดลองเปิดปิด LED ได้แล้ว
แต่แค่ในวงเลน เลยอยากทดลองใช้ผ่าน internet  เราจะเขียน Code กำหนดเปิด Port ยังไงครับ

#include <WiFi.h>

const char* ssid     = "yourssid";
const char* password = "yourpasswd";

IPAddress local_IP(192, 168, 1, 100);
IPAddress gateway(192, 168, 1, 1);
IPAddress subnet(255, 255, 255, 0);
IPAddress primaryDNS(8, 8, 8, 8); //optional
IPAddress secondaryDNS(8, 8, 4, 4); //optional

WiFiServer server(80);

void setup()
    pinMode(2, OUTPUT);      // set the LED pin mode
    digitalWrite(2, HIGH);

   if (!WiFi.config(local_IP, gateway, subnet, primaryDNS, secondaryDNS)) {
    Serial.println("STA Failed to configure");
    WiFi.begin(ssid, password);


int value = 0;

void loop(){
 WiFiClient client = server.available();   // listen for incoming clients

  if (client) {                             // if you get a client,
    Serial.println("New Client.");           // print a message out the serial port
    String currentLine = "";                // make a String to hold incoming data from the client
    while (client.connected()) {            // loop while the client's connected
      if (client.available()) {             // if there's bytes to read from the client,
        char c =;             // read a byte, then
        Serial.write(c);                    // print it out the serial monitor
        if (c == '\n') {                    // if the byte is a newline character

          // if the current line is blank, you got two newline characters in a row.
          // that's the end of the client HTTP request, so send a response:
          if (currentLine.length() == 0) {
            // HTTP headers always start with a response code (e.g. HTTP/1.1 200 OK)
            // and a content-type so the client knows what's coming, then a blank line:
            client.println("HTTP/1.1 200 OK");

            // the content of the HTTP response follows the header:
            client.print("Click <a href=\"/H\">here</a> to turn the LED on pin 2 on.<br>");
            client.print("Click <a href=\"/L\">here</a> to turn the LED on pin 2 off.<br>");

            // The HTTP response ends with another blank line:
            // break out of the while loop:
          } else {    // if you got a newline, then clear currentLine:
            currentLine = "";
        } else if (c != '\r') {  // if you got anything else but a carriage return character,
          currentLine += c;      // add it to the end of the currentLine

        // Check to see if the client request was "GET /H" or "GET /L":
        if (currentLine.endsWith("GET /H")) {
          digitalWrite(2, LOW[img][/img]);               // GET /H turns the LED on
        if (currentLine.endsWith("GET /L")) {
          digitalWrite(2, HIGH;                // GET /L turns the LED off
    // close the connection:
    Serial.println("Client Disconnected.");
