In this video we will learn how to create a web server hosted in ESP32 using MicroPython language for controlling the state of a gpio pin. 

This knowledge can be use for controlling a relay which is popular in home automation projects. For the sake of simplicity…

In previous video, we learned to create a web server on ESP32 acting as a wifi station mode. Now in this video, we will learn another wifi mode which is an Access Point mode.


In Access Point mode, you dont need a router. ESP32 will act as the Access Point…

In this video we will learn to create a web server hosted on ESP32 and display DHT measurement readings on it. We will use AJAX to automatically update the sensor values without refreshing the whole web page.

since we have the esp32-s2 and esp32-s3 QT Py’s designed, we thought there could be some use for a ‘plain’ ESP32 QT Py. Why, when the S2 and the S3 exist? well, first up the &#821…

In this video, we will use our previous knowledge of using DHT sensor discussed in tutorial 11. In tutorial 16 and tutorial 17, we learned to display DHT measurements on a webpage through a web server hosted on esp32. This time, we will use the Thingspeak.com IoT…

In the previous video, we learned to use a RESTful APIs for updating DHT sensor values to Thingspeak server. Data is sent using HTTP POST method. Now in this video, we will do the opposite, that is to request for a  data from a server using the HTTP GET method.…

In this video, we will learn a more complete usage of RESTful APIs which is bidirectional communication with the server that is both sending and requesting of data.

In tutorial 18, I demonstrate sending of data to Thingspeak server using the HTTP POST method while in…

In this video, we will learn to create a basic setup of MQTT system using the ThingSpeak server and an ESP32 using MicroPython language.

We will be using the esp32 to send dht sensor data to Thingspeak server using MQTT Protocol.

In the previous video, I demonstrate the use of MQTT protocol by sending DHT sensor readings to Thingspeak as MQTT broker while the ESP32 serves as MQTT client. The act of MQTT client sending data to MQTT broker is called MQTT publish. 

Now in this video…

In this video, I would like to share to you this simple yet very cool project using a dot matrix display. It is called a Binary Clock and I program it using MicroPython language.
