Hello learners, Welcome to MAKERDEMY's "Advanced ESP32" course. If you are an engineer, a hobbyist or a student, who wants to learn and implement advanced concepts like Over the Air Programming, FreeRTOS and Ultra Low Power Consumption in your ESP32 Projects or Products, you have come to the right place!
This is an advanced level course and experience with ESP32, and Arduino IDE is essential to follow this course. Through an innovative pedagogy of mixing projects and advanced concepts, this course will help you learn the WHY, HOW, and WHAT of the topics covered. For the more curious learners, we have provided ample resources to dive into and continue your learning journey.
On finishing this course, you will get deeper insights into the features of the ESP32 Board, that you didn't even realize. You will be able to make your products or projects user-friendly by implementing OTA Programming and WiFi Manager. You will gain an in-depth understanding of RTOS and its applications. You will understand FreeRTOS and be able to implement it to optimize your projects or products. Finally, you will learn to drastically reduce the power consumption of the ESP32 Board, by implementing Deep Sleep and leveraging the ULP Coprocessor of the ESP32 in your products or projects.
