Description
Course Overview
This course helps beginners learn how to connect microcontrollers like ESP32 to AWS IoT Core, exchange data using MQTT, and build real-world smart IoT applications.
You will start from absolute basics—no prior AWS, cloud, or embedded experience is required. Step by step, you will build a complete IoT system covering hardware, cloud, and mobile application integration.
By the end of this course, you will be able to:
Securely connect ESP32 devices to AWS IoT Core
Publish and subscribe to MQTT topics
Control real hardware from AWS IoT Core and an Android app
Target Audience
Beginners in IoT or AWS
Engineering students
Software developers exploring cloud and hardware integration
Makers and electronics hobbyists
Android developers interested in IoT applications

Section Outcome
Students will build an Android application that communicates with AWS IoT Core to control a real ESP32-based smart home switch (Light ON/OFF).
This completes a full end-to-end IoT solution:
ESP32 Hardware → AWS IoT Core → Android Mobile App
Section 8: Production-Grade Authentication & Authorization Architecture
This section moves beyond basic IoT connectivity and dives into real-world security architecture using Amazon Cognito.
You’ll gain a deep understanding of:
How User Pools authenticate users and issue JWT tokens
How Identity Pools exchange those tokens for temporary AWS credentials
How IAM roles enforce least-privilege access
How mobile and web apps securely access AWS services
How Cognito integrates with AWS IoT Core in production
We also clarify the critical difference between user authentication and device authentication, ensuring you understand when to use Cognito versus X.509 certificates in IoT architectures.
This section equips you with the architectural knowledge required to design secure, scalable, and production-ready IoT systems — not just demo projects.
Section 9: MQTT Protocol Explained (From Basics to AWS IoT Core)
Learn the MQTT protocol in depth, the backbone of modern IoT communication.
This section explains how publish/subscribe works, how topics are structured, how QoS affects reliability, and how AWS IoT Core securely manages MQTT traffic at scale. You’ll gain a clear mental model of how messages flow between devices, cloud, and applications.
Section 10: Security & Scalability Best Practices for IoT Applications
Move beyond demos and learn industry best practices for building secure and scalable IoT solutions.
This section covers secure access patterns, least-privilege IAM usage, scalable topic design, device lifecycle management, and cost-aware architecture decisions—helping you build applications that are ready for real production environments.
