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.

In this video, you will learn how to use the ESP32 to host a webpage for controlling something like your lights, appliances, etc in your home.

The ESP32 is configured to station mode (STA) so this needs a wifi router in between.

Last time, I posted tutorial on how to use the ESP32 configured as WiFi Station. In order for us to control something in our web server, we need to connect to ESP32 and our device in the same Access Point or router. Now we will directly connect to our ESP32…

In this tutorial, we will focus to the Bluetooth classic. If you have experience using the commonly use bluetooth module like HC-05/06, the usage is almost the same. It uses a standard serial protocols and functions

We will start using the example sketch…

In this video we will learn how to install Thonny Python IDE for MicroPython learning and development. I will also guide you step-by-step on how to flash a MicroPython firmware to ESP32 development.

Recently, one of my friend from South Korea reached out with me to introduced this Gorilla Cell ESP32 development kit which is composed of Gorilla Cell ESP32 Shield by which ESP32 fits nicely on it, an ESP32 development board, and 80 pieces of Gorilla cells…

In this video, we will look at the necessary procedures for MicroPython language environment in using the Gorilla Cell Development kit.

I divided it into 3 simple steps:
1. ESP32 USB driver installation.
2. Thonny Python IDE installation.
3. Flashing MicroPython…

In this video, I will introduce the Gorilla Cell ESP32 development kit. A kit that is designed to have countless hours of exciting experiment and tinkering in exploring ESP32 microcontroller using MicroPython language.

More details will be posted at:

In this video, we will look at the Gorilla Cell ESP32 Shield. It provides GPIO expansion through the male pin headers to allow complete beginners to explore microcontrollers easily, avoiding unnecessary confusion in using breadboards. It is intuitively designed…

In this video, we will look at the input and output devices available in the Gorilla Cell Development Kit.

A module in a kit can be either an input device or an output device. 

It is an input device if we read or get data from it for example a switch or…

In this video, we will be looking at LED. We will learn on how to control it by turning it ON or OFF with MicroPython language.


LED stands for Light Emitting Diode. It is an electronic component that emits light when a sufficient voltage is applied on its…

In this video, we will look at traffic light led module. It is a small model or miniature of traffic light. We will learn on how control using ESP32 with MicroPython.
