Creating and using your own WiFi library in the Arduino IDE: code and instructions

#include "MyWiFiLib.h"

void setup() {
  Serial.begin(115200);
  delay(1000);

MyWiFiLib wifiLib;
  const char* ssid = "wifi"; // Zdefiniuj swoją nazwę sieci WiFi
  const char* password = "abc123abc123";   // Zdefiniuj swoje hasło do sieci WiFi

  wifiLib.connectToWiFi(ssid, password);

  // Dalsze operacje
}

void loop() {
  // Działania w pętli
}

#ifndef MyWiFiLib_h
#define MyWiFiLib_h

#include <Arduino.h>
#include <ESP8266WiFi.h>

class MyWiFiLib {
public:
  MyWiFiLib();
  void connectToWiFi(const char* ssid, const char* password);
};

#endif

#include "MyWiFiLib.h"

MyWiFiLib::MyWiFiLib() {
  // Konstruktor, jeśli potrzebujesz
}

void MyWiFiLib::connectToWiFi(const char* ssid, const char* password) {
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to WiFi...");
  }
  Serial.println("Connected to WiFi");
  Serial.println(WiFi.localIP());
  WiFi.hostname("D1mini");
  Serial.println(WiFi.getHostname());
}

MyWiFiLib wifiLib;

Quote:

The line MyWiFiLib wifiLib; creates an instance of the MyWiFiLib class object named wifiLib. This is an initialisation of the MyWiFiLib library object that was previously defined in the "MyWiFiLib.h" header file.

After creating an instance of the wifiLib object, its functions and methods, such as connectToWiFi(), can be used to perform operations inside this library. In this case, the connectToWiFi() function is called on the wifiLib object with the given ssid and password arguments, which will attempt to connect the ESP8266 module to a WiFi network with the given name (SSID) and password (password).

Using the wifiLib object allows easy use of the MyWiFiLib library functions, which helps organise the code and allows these functions to be used in different places in the program when needed.

maybe someone can suggest where to look for some information on how to create these types of libraries?

Creating libraries for Arduino is the same as for C++ and should be followed.
