Hello, I've searched a lot for an answer to this but no luck, so here I am. I can connect my Arduino rev2 wifi to a PC ( running EventGhost ) and I can direct it to access a web page, but rather than the Arduino opening the page, I need it to open the page on the web server ( the same PC, web server provided by event ghost. ) Here is the code:
#include <EtherEvent.h>
#include <WiFiNINA.h>
#include <WiFi.h>
#include <SPI.h>
#include "arduino_secrets.h"
#include <hd44780.h>
#include <Wire.h>
#include <hd44780ioClass/hd44780_I2Cexp.h> // include i/o class header
WiFiClient client;
int count=0;
int maxcount=1;
int sensorPin0 = A0; //sensor pins
int sensorPin1 = A1;
int sensorValue0;
int sensorValue1;
int limit = 380;
int port = 8080;
const char pcbeast[] = "http://192.168.0.113/?shutdown";
hd44780_I2Cexp lcd;
void printCurrentNet()
{
// print the SSID of the network you're attached to:
Serial.println("SSID: ");
Serial.println(WiFi.SSID());
// print the MAC address of the router you're attached to:
byte bssid[6];
WiFi.BSSID(bssid);
Serial.println("BSSID: ");
// lcd.print("BSSID: ");
// lcd.print('/n');
// printMacAddress(bssid);
//print the received signal strength:
long rssi = WiFi.RSSI();
Serial.println("signal strength (RSSI): ");
Serial.println(rssi);
//print the encryption type:

Serial.println("Encryption Type: ");
Serial.println(encryption, HEX);
}
void printWiFiData()
{
// print your board's IP address:

// if you get a connection, report back via serial:

// Make a HTTP request:

client.println();

}There may be some redundancy in the headers wrt networking but this is still a learning process for me. Any feedback appreciated.
