Learn about the ESP32, a powerful microcontroller, which has so many features like Wifi, Bluetooth, Dual-Core processors and so much more, all packed into one small unit. That too at a very low price.

This course is designed to explore all of these features with a very practical approach. If there is one goal of our course, it's to give you enough knowledge and confidence to go out there and build your own projects, which is the true essence of this course.

Overview of the Course:

This course is suitable for beginners and currently stands with 90+ lectures which last about nearly 7.5 hours. By taking this course, you'll be able to learn everything that one needs to know about ESP32 and hence give you enough confidence to build projects on your own.

We start off with a brief introduction to IoT and then move on to ESP32's hardware specifications and finally, we learn and implement the various rich features it provides us with.

Most of our course is filled with demonstration videos - writing code, wiring up circuits, and getting the desired output. These are accompanied by theoretical videos for a better understanding. But this is not a course wherein we just use slides and explain everything in a monotonous voice.

To keep things interesting, we've included quizzes and coding assignments as well. These are not too difficult that will make you tear your hair out, but just hard enough to pique your interests.

To make it easier for you to keep in track with the course, we have added external resources which include codes & circuits that we've used in the videos as well as proper documentation with all the information that has been covered in the theoretical videos and much more.

Complete with working files and code samples, you’ll be able to work alongside the instructors as you work through each concept, and will receive a verifiable certificate of completion upon finishing the course
