I'm new Arduino and I would like you to help me. I would like to have a public IP so that anyone can get access to it, not only from domestic domain. What could I do?. I'm using Arduino Uno, Arduino Ethernet Shield w5500 and a RTC. My code:
#include <SPI.h>
#include <Ethernet.h>
#include "RTClib.h"
#include <EEPROM.h>
#define time 1
// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network:
byte mac[] = {0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED};
IPAddress ip(192, 168, 0, 177);
// Initialize the Ethernet server library
// with the IP address and port you want to use
// (port 80 is default for HTTP):
EthernetServer server(80);
//----------------------------------------------------------------------------------------------------------------
int i=0;
String hora="";
String readString;
RTC_DS1307 RTC;
void setup() {
pinMode(2,OUTPUT);
// Open serial communications and wait for port to open:
Serial.begin(9600);
RTC.begin(); // Inicia la comunicaci¢n con el RTC
RTC.adjust(DateTime(__DATE__, __TIME__)); // Establece la fecha y hora (Comentar una vez establecida la hora)
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only
}
Serial.println("Sistemas Digitales");
// start the Ethernet connection and the server:
Ethernet.begin(mac, ip);
// Check for Ethernet hardware present
if (Ethernet.hardwareStatus() == EthernetNoHardware) {
Serial.println("Ethernet shield no se encontro. No se puede correr el programa sin el hardware. :(");
while (true) {
delay(1); // do nothing, no point running without Ethernet hardware
}
}
if (Ethernet.linkStatus() == LinkOFF) {
Serial.println("El cable Ethernet no esta onectado.");
}
// start the server
server.begin();
Serial.print("El servidor esta en: ");
Serial.println(Ethernet.localIP());
}
void loop() {
// listen for incoming clients
delay(1000);
DateTime now = RTC.now(); // Obtiene la fecha y hora del RTC
EthernetClient client = server.available();
if (client) {
while (client.connected()) {
if (client.available()) {
//---------------------------------------------------------------------------------------------------------------------------------
char c = client.read();
if(i==11 || i==12 || i==16 || i==17){
if(i==16){
hora +=':';
}
hora += c;
}
if(readString.length()< 100){
readString += c;
}
i++;
//Este escribe el texto en pantalla letra por letra
Serial.write(c);
// if you've gotten to the end of the line (received a newline
// character) and the line is blank, the http request has ended,
// so you can send a reply
if (c == '\n') {
Serial.println("acabo lectura");
Serial.println(hora);
Serial.println(readString);
client.println("HTTP/1.1 200 OK"); // Enviar una respuesta tipica
client.println("Content-Type: text/html");
client.println("Connection: close");
client.println("Refresh: 10");
client.println();
client.println("<!DOCTYPE HTML>");
client.println(" <html lang='en-US'>");
client.println("<html>");
client.println("<head><meta charset='UTF-8'><title>Sistemas Digitales</title></head>");
client.println("<body>");
client.println("<div style='text-align:center;'>");
client.print("<h1>Fecha y hora del servidor:");
client.print(now.day(), DEC);
client.print('/');
client.print(now.month(), DEC);
client.print('/');
client.print(now.year(), DEC);
client.print(' ');
client.print(' ');
int horini;
horini=now.hour();
String horartc = "0";
if(horini<10){
horartc += horini;
}else{
horartc= String(horini);
}
client.print(horartc);
client.print(':');
int minuto;
minuto=now.minute();
String mainut;
if(minuto<10){
mainut='0'+ String(minuto);
}else{
mainut= String(minuto);
}
client.print(mainut);
client.println("</h1>");
client.println("<form method='get'>");
client.println("<br /><h2>¿A que horas le quiere dar de comer al chucho?</h2><br />");
client.println("<input type='time' name='hora'>");
client.println("<br/><h2>que dias lo quiere alimentar?</h2><br />");
//dias en checkbox
//client.println("<label><input type='checkbox' name='cbox1' value='?LunesOn'>Lunes</label><br><label><input type='checkbox' name='cbox2' value='?MartesOn'>Martes</label><br><label><input type='checkbox' name='cbox3' value='?MiercolesOn'>Miercoles</label><br><label><input type='checkbox' name='cbox4' value='?JuevesOn'>Jueves</label><br><label><input type='checkbox' name='cbox5' value='?ViernesOn'>Viernes</label><br><label><input type='checkbox' name='cbox6' value='?SabadoOn'>Sabado</label><br><label><input type='checkbox' name='cbox7' value='?DomingoOn'>Domingo</label><br>");
client.println("<input type='submit' value='Enviar' id='enviar'> ");
client.println("</form>");
if (readString.length() >0) {
Serial.println("hora del rtc");
String horiux = horartc +':'+ mainut;
Serial.println(horiux);
EEPROM.put(0, hora);
if(EEPROM.get( 0, hora ) == horiux){
digitalWrite(2, HIGH);
delay(10000);
digitalWrite(2, LOW);
delay(60000);
}
readString="";
i=0;
hora="";
client.println("</body>");
client.println("</html>");
delay(1);
// close the connection:
client.stop();
}
}
}
}
}
}
There it is a part of the code:
IPAddress ip(192, 168, 0, 177);
I would like to make that IPto be public domain so you can get access anywhere instead of neededing to be in the same ethernet connection.
Any help would be wonderful, thanks for your time.
