#include <WiFi.h>
#include <PubSubClient.h>

const char* ssid = "your_wifi_ssid";
const char* password = "your_wifi_password";
const char* mqttBroker = "your_broker_ip_address";
const int mqttPort = 1883;
const char* mqttUser = "your_mqtt_username";
const char* mqttPassword = "your_mqtt_password";

WiFiClient espClient;
PubSubClient mqttClient(espClient);

void setup() {
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
  }

  mqttClient.setServer(mqttBroker, mqttPort);
  mqttClient.setCredentials(mqttUser, mqttPassword);
}

void loop() {
  if (!mqttClient.connected()) {
    reconnect();
  }
  mqttClient.loop();

  // Publish a message to a topic
  mqttClient.publish("your/topic", "Hello from ESP32");
  delay(5000);
}

void reconnect() {
  while (!mqttClient.connected()) {
    if (mqttClient.connect("ESP32Client")) {
      // Subscribe to any topics if needed
      mqttClient.subscribe("your/subscribe/topic");
    } else {
      delay(5000);
