const char *pass = "academyiot@23";
These lines define the MQTT broker details (address, username, password, and port) and
the WiFi credentials (SSID and password) for connecting the ESP8266 to a Wi-Fi
network.

Client Initialization:
WiFiClient espClient;
PubSubClient client(espClient);
These lines initialize the Wi-Fi and MQTT clients.

DHT Sensor and GPIO Configuration:

const int DHTPin = D4;

15
const int switch1 = D1;
const int switch2 = D2;
DHT dht(DHTPin, DHTTYPE);
These lines define the GPIO pins for the DHT sensor and switches (lamps). The DHT
sensor is connected to GPIO D4, and two switches are connected to GPIO D1 and D2.

Wi-Fi Setup Function:

void setup_wifi()
This function is responsible for connecting the ESP8266 to the specified Wi-Fi network.

MQTT Callback Function:

void callback(String topic, byte* message, unsigned int length)
This function is called whenever a message is received from the MQTT broker. It
interprets the message and performs actions based on the topic and message content. In
this case, it controls the state of the switches (lamps) based on the received MQTT
messages.
