your computer using a USB cable. ## Open the Arduino IDE and select the appropriate board and port from the "Tools" menu. ## Copy and paste the complete code into the Arduino IDE. ## Click the "Upload" button (or use the shortcut Ctrl+U) to compile and upload the code to the ESP32. ## Wait for the upload process to finish, ensuring there are no errors. ## Once the code is uploaded, disconnect the ESP32 from the computer. ## Power on the ESP32 by connecting it to a suitable power source. # Open the serial monitor and set the baud rate to 115200. Then, check the connection status of the ESP32 by monitoring the output in the serial monitor. # Use the MQTTX client to establish a connection with the MQTT broker and publish messages such as <code>Hi, I'm MQTTX</code> to the ESP32.   +, Ensure that the ESP32 dev library is installed, then go to libraries in the Arduino IDE and download PubSubClient. PubSub, short for Publish/Subscribe, is a messaging pattern where senders (publishers) distribute messages to receivers (subscribers) without directly communicating with them. Publishers send messages to a central hub (broker), which then distributes them to all interested subscribers based on their topic subscriptions. This is useful to conserve data when trying to share information, because rather than multiple different connections between the publisher and each subscriber, the publisher only needs to send the information once.  +,
To follow along with this tutorial, you will need the following components: * An ESP32 board (I’m using the ESP32 DevKitC) * The Arduino IDE installed on your computer * The ESPAsyncWebServer and AsyncTCP libraries installed on your Arduino IDE You can find the links to download the libraries and the complete code for this project at the end of this post.  +, You must check out [https://www.pcbway.com/ PCBWAY] for ordering PCBs online for cheap!

The ESP32 will then use that value to adjust the duty cycle of a PWM signal, which is a digital signal that switches between high and low states at a certain frequency. By changing the ratio of the high and low states, we can change the average voltage applied to the LED, and thus its brightness.<br /><br />The inbuilt LED is connected to GPIO2, which is one of the pins that supports PWM (Pulse Width Modulation). PWM is a technique that allows us to vary the brightness of the LED by changing the duty cycle of a digital signal. The ESP32 has 16 PWM channels that can be configured to different frequencies and resolutions. By using the <code>ledcSetup()</code> and <code>ledcWrite()</code> functions, we can set up a PWM channel for the inbuilt LED and write a value between 0 and 255 to adjust its brightness. We can also use the <code>Blink</code> example sketch from the Arduino IDE to make the inbuilt LED blink with a certain interval. The inbuilt LED is useful for testing and debugging purposes, as well as for creating simple projects that involve lighting effects.<br /><br />To create the web server, we will use the ESPAsyncWebServer library, which is an asynchronous web server library for the ESP32 and ESP8266. This library allows us to handle multiple web requests and responses without blocking the main loop of the ESP32, which can improve the performance and responsiveness of our web server. We will also use the AsyncTCP library, which is a dependency of the ESPAsyncWebServer library and provides low-level TCP communication between the ESP32 and the web browser.<br /><br />To create the web page, we will use HTML, CSS, and JavaScript. HTML is the markup language that defines the structure and content of the web page.<div class="mw-highlight mw-content-ltr" dir="ltr"><pre><span></span><span class="cp"><!DOCTYPE HTML></span><span
