Course Description

This comprehensive, 10-class course is your definitive guide to the powerful ESP32 microcontroller, designed for aspiring engineers, hobbyists, and developers eager to enter the world of the Internet of Things. We start from the ground up, introducing you to the ESP32's unique architecture and programming environment.

The curriculum is structured to progressively build your skills, moving from basic GPIO control and analog I/O to the ESP32's most compelling features: Wi-Fi and Bluetooth. 

What you will Learn: 

  • ESP32 Fundamentals: You will gain a solid understanding of the ESP32 microcontroller's architecture, key features, and how to program it using the Arduino IDE. You'll master the basics of digital and analog I/O, including advanced techniques like PWM.
  • Wireless Communication: The course's core focus is on the ESP32's connectivity. You will learn how to:
    • Connect the ESP32 to a Wi-Fi network.
    • Host your own web server to control devices from a browser.
    • Use Bluetooth Classic and BLE for communication with smartphones and other devices.
  • IoT Protocols and Cloud Integration: You will move beyond local control and learn to connect your projects to the cloud. This includes understanding and implementing the MQTT protocol for seamless communication with IoT platforms and dashboards.
  • Advanced Programming Techniques: To make your projects more efficient and robust, you will learn to use interrupts for event-driven programming, hardware timers for precise control, and Deep Sleep mode to create battery-powered, long-lasting devices.
  • Project-Based Learning: The course is centered around hands-on projects. You will build and debug practical applications at every stage, culminating in a final capstone project where you create a fully functional, cloud-connected weather station.

First Steps with ESP32: Introduction to the ESP32, board variants, and setting up the Arduino IDE. Hands-on: Uploading your first "Blink" sketch.

GPIO and Digital Control: Understanding the ESP32 pinout. Hands-on: Building a traffic light simulation with LEDs and controlling an LED with a push button.

PWM and Analog I/O: Learn how to use PWM for dimming LEDs and the ADC to read sensor values. Hands-on: Creating a light-sensitive circuit with a photoresistor.

Connecting to the Network: Master Wi-Fi basics and connect your ESP32 to a network. Hands-on: Writing a Wi-Fi scanner and displaying network information.

ESP32 as a Web Server: Learn to host a web server on the ESP32. Hands-on: Controlling an LED from a web page on your smartphone.

Bluetooth Essentials: Explore Bluetooth Classic and BLE. Hands-on: Controlling a servo motor from your smartphone via a Bluetooth terminal app.

MQTT and IoT Platforms: Understand the MQTT protocol for cloud communication. Hands-on: Publishing sensor data to a cloud platform like Adafruit IO.

Interrupts and Timers: Write efficient, non-blocking code. Hands-on: Using interrupts to count button presses without delay().

Deep Sleep for Battery Power: Learn how to use low-power modes. Hands-on: Creating a device that wakes up, takes a reading, and goes back to sleep.

The Smart Weather Station: Integrate all learned skills into a final project. Hands-on: Building a complete weather station that sends temperature and humidity data to a cloud dashboard.
