ESP8266/ESP32 and MQTT | Control GPIO & DHT11 Sensor
In this video, we demonstrate how to control 4 LEDs and read data from a DHT11 sensor using an ESP8266 microcontroller and the EspMQTTClient library.
What You'll Learn:
• Setting up the EspMQTTClient library for easy MQTT integration
• Controlling multiple LEDs via MQTT topics
• Reading temperature and humidity data from a DHT11 sensor
• Publishing sensor data to MQTT topics
• Subscribing to MQTT topics to control devices
Components Used:
• ESP8266 Microcontroller
• 4 LEDs
• DHT11 Temperature and Humidity Sensor
• MQTT Broker (test.mosquitto.org)

Step-by-Step Guide:
• Setup ESP8266: Connect your ESP8266 to the WiFi network.
• Install Libraries: Ensure you have the EspMQTTClient and DHT libraries installed.
• Wiring: Connect 4 LEDs and the DHT11 sensor to your ESP8266.
• Coding: Implement the code to control LEDs and read DHT11 data via MQTT.
• Testing: Use an MQTT client to publish and subscribe to topics to control the LEDs and monitor sensor data.
