The Ultimate
ESP32
course Bundle

FOUR amazing courses to help you master the ESP32.

SPECIAL BONUS: Maker Education Revolution (eBook)

ESP32 For Busy People

Learn how to use the ESP32 in place of the Arduino to do things such as controlling LEDs, reading button and potentiometer states, drive displays and motors, read data from digital and analog sensors (including internal sensors), communicate with the Internet, and communicate with Bluetooth devices.

ESP32 Unleashed

This course is perfect for people who have good working knowledge of the ESP32. If you don’t, we recommend starting with ESP32 For Busy People.

Learn how to create a device that integrates the ESP32 development kit with several hardware components and Cloud services.

Node-RED & ESP32

With this course, you will learn how to design and build an automated control system using Node-RED and the ESP32. This course will guide you through the construction of an automated control system.
Along the way, you will learn a great deal about useful technologies such as the Node Red programming environment and MQTT.

MicroPython with the ESP32

With this video course, you will learn how to use the MicroPython programming language with the ESP32 microcontroller. MicroPython is a high-level programming language specifically designed for microcontrollers and resource-limited embedded devices. Think of MicroPython as "Python for Microcontrollers".

Plus special bonus:

Conventional education is struggling to provide the learning environment necessary to help raise the future innovators, problem solvers, and entrepreneurs that advanced societies need. While efforts to transform education in that direction are underway, they are too slow and not decisive enough, resulting in too many of our children being left behind.

In this book, Dr Peter Dalmaris argues that it does not have to be like that. Using Maker Education as a model for education in the 21st century, Peter explains how teachers, parents, and learners can apply the educational methods of inventors and innovators for the benefit of their students and children.

Course details for ESP32 For Busy People

What can you make with a dual-core microcontroller, that has integrated Bluetooth and WiFi, lots of pins, storage and communications, using your familiar Arduino tools?

With the ESP32, you can prototype your idea quickly. 

You can use the familiar Arduino tools, programming language, and libraries. 

The ESP integrates WiFi and Bluetooth, many GPIOs, analog input and output capabilities, many device interconnection protocols, a fast dual-core processor. And it has lots of storage and RAM, so your sketches can grow as your projects grow.

If you are already using the Arduino, then the ESP32 is an excellent choice. You can replace the Arduino Uno or other Atmega based boards with an ESP32 dev kit, and add new capabilities to your projects.

Who is this course for?

This course is perfect for people who have at least basic working knowledge of the Arduino.

If you don’t, we recommend starting with Arduino Step by Step Getting Started.

Why take this course?

The ESP32 is a powerful, low-cost microcontroller that fits well in the Arduino ecosystem.

If you are already using the Arduino in your projects, then you'll love what the ESP32 can do.

The ESP32 packs a lot of power: lots of processing power, GPIO's communications options, including a full array of wireless capabilities, and integrated sensor.

This course will help you get up and running with the ESP32 quickly.

With the ESP32, you can get a lot more capacity to build more interesting projects, almost for free.

The ESP32 is not a plug-in replacement for the Arduino. While it shares much of the Arduino’s programming and GPIO interface, you still need to learn the basics before you can deploy it.

This is the purpose of this course: to provide with you a learning resource that can help you become productive with the ESP32 quickly.

In this course, I have included numerous mini-projects to demonstrate how to use capabilities such as GPIO read and write, classic Bluetooth, Bluetooth Low Energy, WiFi, digital to analog conversion, touch sensors, and more.

Larger projects will also show you how to create simple Internet of Things and Bluetooth applications, to name a few.

Course details for Node-RED & ESP32

With this course, you will learn how to design and build an automated control system using Node-RED and the ESP32.

Node-RED is a lightweight graphical programming tool. You can use it to join a variety of hardware and software components and create applications such as the automated terrarium controller in this course.

Node-RED is used in a range of settings. Makers to create home automation applications and organisations use it to automate their factory floors, among many other possibilities.

The ESP32 is a powerful low-cost microcontroller with build-in Wifi that we can program with the familiar Arduino IDE. Its "call to fame" is that it makes it easy for anyone that is familiar with the Arduino to leverage their knowledge and create gadgets that need more memory and processing power than what the Arduino Uno can provide, in addition to Wifi and Bluetooth. All this at a lower price point.  

Who is this course for?

To complete this project you do need to be comfortable with a few technologies and skills. 

Here is a list:

  • Be familiar with the Arduino and ESP32.
  • Be familiar with Raspberry Pi.
  • Be familiar with Javascript.
  • Be comfortable on the command line.
  • Be able to assemble simple circuits.
  • Not be afraid to make a mistake (and fix it).

If you have completed these two courses:

... or are confident that you have the skills listed above, then you are ready to start with this new project and challenge.

Why take this course?

This course will guide you through the construction of an automated control system. The deliverable is a Terrarium controller.

Along the way, you will learn a great deal about useful technologies such as the Node Red programming environment and MQTT.

This course is perfect for Makers who are familiar with the ESP32 and are interested in learning how to use it alongside Node-RED.

A project like this gives us an opportunity to branch out and explore. 

In this project, the primary learning objective is Node Red and MQTT. However, it presents an opportunity to learn more.

You will learn how to use Google’s Drive and Sheet APIs and IFTTT (If This Then That). These are excellent representative technologies of what is available to Makers right now.

Both technologies are mature, and very useful, no fluff.

With Node-RED, you will be able to easily integrate both in your flows.

Course details for MicroPython with the ESP32

MicroPython is a high-level programming language specifically designed for microcontrollers and resource-limited embedded devices. Think of MicroPython as "Python for Microcontrollers".

What MicroPython has "taken" from Python is the language architecture, the programming philosophy for code readability, and millions of programmers that already know how to use Python.

MicroPython is as easy as Python to learn, and follows Python’s tradition for excellent development tools and documentation.

Who is this course for?

This course is for anyone looking for the easiest (yet still powerful) way to program a micro-controller.

Familiarity with Python is not necessary - with this course you will learn everything you need.

If you already know Python, then this course will help you get started with MicroPython and use it to program the ESP32.

Ideally, you have a basic understanding of electronics, and are familiar with the Arduino platform*.

* If you are not familiar with the Arduino platform and have a basic understanding of electronics, I recommend you consider Basic Electronics for Arduino Makers and Arduino Step by Step Getting Started first.

Why take this course?

Because it will help you learn MicroPython on the ESP32 in a practical and enjoyable way.

Once you complete this course, you will be able to:

  • Use MicroPython with the ESP32, as well as virtually any other board that supports the µPython language (such as the BBC Micro:Bit, WiPy, Raspberry Pi Pico, etc.)
  • Use MicroPython to program gadgets that include displays, motors, switches, and communications.

The course uses a hands-on approach with many mini-projects and two capstone projects that will help you consolidate your new knowledge.

Once you learn the basics of MicroPython, you can use your skills across multiple hardware targets. 

At the time of publication of this course, MicroPython has support for the original Myboard v1 and D-series, as well as third-party boards such as the STM32  Nucleo and Discovery boards, the Espruino Pico, the Raspberry Pi Pico, the WiPy, the ESP8266 and ESP32, the TinyPico, and the BBC Micro:Bit.

And the list is growing.
