Categories: Embedded Systems, Internet of Things
About Course
“Complete IoT Automation with ESP32 – From BLE to Cloud” is a comprehensive 10-week program designed to take you from IoT basics to building secure, production-ready automation systems using the ESP32. Through hands-on labs, real-world projects, and a final capstone, you’ll learn how to connect devices, collect and process data, integrate with cloud platforms, and implement professional security practices. Each module blends theory with applied projects — from setting up your ESP-IDF environment to deploying a secure cloud-connected home automation system. By the end of this course, you’ll not just understand IoT concepts — you’ll have the skills and confidence to design, code, and deploy scalable IoT solutions for real-world applications.
