Explore the origins of communication, the internet of things concept, and the IoT architecture, ingredients, protocols, development boards, platforms, IoT types, and future opportunities using ESP32.
Explore how the internet of things connects everyday devices—from clocks to lights—to the internet, enabling smart homes, industry, and agriculture. Trace IoT’s evolution from content, services, and people toward architecture.
Explore the four-layer IoT architecture—smart things, gateways, middleware, and the application interface—and how Zigbee, Bluetooth, and Wi‑Fi gateways connect devices to the internet and Azure IoT.
Explore Arduino IoT cloud overview and pricing, including devices, things, dashboards, triggers, and OTA updates, and compare free, maker, team, school, and enterprise plans.
Connect the LED and LDR to the ESP32, wiring 3.3V and ground with D2 for the LED and D15 for the LDR, using a 10K pull-up.
Create an ESP32 dashboard to monitor LDR readings in real time on the Arduino IoT cloud, using a gauge, chart, and LED controls.
Are you curious about how smart devices work? Want to explore the world of IoT (Internet of Things) but don’t know where to start? This free beginner-friendly course is the perfect starting point for you!
In this course, you'll learn the basics of IoT—how connected devices communicate, how data flows between sensors and the cloud, and how you can control and monitor devices from anywhere in the world. No previous experience is required!
We’ll introduce you to the ESP32 microcontroller and walk you through setting up your first IoT project using the Arduino IoT Cloud. You’ll build a practical system to control an LED and monitor light levels using an LDR (Light Dependent Resistor).
The course is hands-on, easy to follow, and designed for total beginners. By the end, you’ll have built your first working smart project, created a cloud dashboard, and gained the confidence to explore more advanced IoT applications.
Whether you’re a student, hobbyist, or just curious about technology, this course will help you get started in the exciting world of IoT—for free!
You’ll learn how to:
Connect physical sensors and actuators
Create a dashboard to monitor and control devices from anywhere
Understand cloud-based IoT workflows
This course is ideal for students, hobbyists, and professionals who want to get started with real-world IoT applications.
