Now that you have learned the basics of the ESP32, it is time to experience the true power of this technology.
It is time to create an application that will stretch your existing knowledge and skills.
An application that will introduce you to new possibilities.
With ESP32 Unleashed, you have this opportunity.
ESP32 Unleashed give you a challenging project and the guidance you need to complete it.
A project that combines...
...to deliver a real, useful, working gadget.
A project like this can stretch your hungry mind and fill it with new delicious knowledge.
ESP32 Unleashed is a project course
This course is perfect for people familiar with the ESP32, especially graduates of ESP32 For Busy People.
It is a guided project, designed to teach you how to use modern tools to create modern embedded applications based on the ESP32.
Course hardware requirements
To complete this course, you will need a few hardware components.
You can find a list here (this page will open in a new browser window).
Are there any prerequisites?
Yes. To complete this course, you will need to be familiar with the ESP32 dev kit.
If you are not familiar with the ESP32 dev kit, consider completing ESP32 For Busy People before enrolling to ESP32 Unleashed.
You can take advantage of the ESP32 Unleashed launch discounting and purchase both for US$25 each.
In this course, you will learn how to make an IoT gadget.
You'll use the knowledge you acquired in ESP32 For Busy People.
You'll learn new knowledge so that you can integrate new components and tools.
This course is action-packed. Here are some highlights:
As always, the course follows the familiar Tech Explorations format, which includes all schematic wiring diagrams and demo sketches, a logical course structure, high-quality video and audio, and thoughtful and calm delivery.
In addition, in this course, you can also download the complete PlatformIO project file, which also includes every single Git commit I have made during the recording of the lectures.
