Arduino uno network card

I have the following questions see picture for more info ;)

I have more than 500 devices in my network and on several buildings.

And i want to configure the devices over the internet with port-forwarding in a secure router to the devices. Is there a solution for this project?

Image arduino

Thanks in advanced

Hans

What should we see on the picture? do you want to use Ethernet or WiFi?

@ Juraj

I want to go over Ethernet

I want to go over Ethernet

try to add Ethernet library and code from WebServer example to your sketch and use Verify to see if the sketch fits into Uno memories

I want to combine 2 sketch

For the orduino uno i have the folowing;

/* Arduino Tutorial: Learn how to use an LCD 16x2 screen
More info: http://www.ardumotive.com/how-to-use-an-lcd-dislpay-en.html */

//Include LCD library
#include <LiquidCrystal.h>

// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

void setup() {
// set up the LCD’s number of columns and rows:
lcd.begin(16, 2);
// Print a message to the LCD.
lcd.print(“Bla bla”);
}

void loop() {
// set the cursor to column 0, line 1
// (note: line 1 is the second row, since counting begins with 0):
lcd.setCursor(0, 1);
//Print a message to second line of LCD
lcd.print(" Bl bla");
}

For the network card i have this;

#include <Wire.h>

#include <TFT.h>

/*
Web Server

A simple web server that shows the value of the analog input pins.
using an Arduino Wiznet Ethernet shield.

Circuit:

  • Ethernet shield attached to pins 10, 11, 12, 13
  • Analog inputs attached to pins A0 through A5 (optional)

==============================================

Is it possible to combine the 2 sketches?

aduinoroot: Is it possible to combine the 2 sketches?

sorry, but if you can't do this simple thing then let it be

does it Verify? what sizes are reported? why did you include SD?

Juraj:
does it Verify? what sizes are reported? why did you include SD?

Otherwise i need to much memory see below (in Dutch sorry)

1570 bytes (76%) van het dynamisch geheugen. Resteren 478 bytes voor lokale variabelen. Maximum is 2048 bytes

And on my sd card is the index.htm file witch i need for replacing the lines on my LCD 1602 http://prntscr.com/o0eono

and the flash memory usage?

Its done and working fine thanks for the help
