This course features Coursera Coach! A smarter way to learn with interactive, real-time conversations that help you test your knowledge, challenge assumptions, and deepen your understanding as you progress through the course. Mastering Hardware Protocols with ESP32 and Arduino is designed to equip learners with essential skills for understanding and implementing various communication protocols like UART, I2C, SPI, OneWire, and non-standard protocols such as DHT11 and DHT22. The course begins with an introduction to the fundamentals, helping learners grasp the importance of hands-on practice alongside theoretical concepts, ensuring they build practical skills from the outset. Through engaging video lessons, students will dive into topics such as setting up the VSC PlatformIO program in Arduino IDE, differentiating wireless protocols, and using tools like PulseView for signal analysis. The course offers a step-by-step exploration of each protocol, from theory to real-world application, with a focus on using logic analyzers and various Arduino devices. By the end of the course, learners will have a comprehensive understanding of serial communication, sensor interfacing, and how to analyze and optimize signals. Whether working with basic hardware like the DS18B20 temperature sensor or advanced setups involving the ESP32, this course ensures that you not only understand the protocols but also how to implement them efficiently for different projects. This course is ideal for electronics enthusiasts, makers, and developers who wish to advance their knowledge of hardware communication protocols and work with embedded systems. It is suitable for individuals with a basic understanding of electronics and programming, though a prior background in Arduino or microcontrollers is recommended.

Syllabus

Introduction

In this module, we will introduce the course content and provide a roadmap of what you will learn. We will also cover the prerequisites for successful participation, along with a focus on practical experience before theory. Additionally, you will familiarize yourself with the necessary tools, resources, and disclaimers associated with the course.

Basics logic analyzer and bit operators

In this module, we will introduce you to the fundamentals of logic analyzers and bit operators. We will explore their key characteristics, practical use cases, and differences from oscilloscopes. Additionally, you will practice essential bitwise operations and reinforce your learning through hands-on exercises.

PulseView Basics

In this module, we will introduce you to PulseView, including its key features and advantages for your projects. We will guide you through downloading and configuring the software, as well as connecting a logic analyzer. Additionally, we’ll cover essential settings for sample rates, frequency, baud rates, and teach you how to produce and analyze signals effectively.

UART

In this module, we will cover the fundamentals of UART communication and how it fits into serial data transmission. You will learn how to implement UART on both Arduino Uno and ESP32, convert data formats, and understand key concepts like parity bits, baud rates, and logic levels. We’ll also explore practical applications, such as sensor analysis, to solidify your understanding.

OneWire

In this module, we will introduce you to the OneWire protocol and its applications, focusing on how to use the DS18B20 temperature sensor. We’ll explore key concepts like wiring, data analysis, and resolution adjustments, while also guiding you through retrieving data using the OneWire library for seamless integration in your projects.

Non-standard protocols- DHT11 (DHT22)

In this module, we will explore the DHT11 and DHT22 sensors, covering the wiring, signal analysis, and how to decode the data they generate. You’ll also gain insight into the DHT library, which simplifies interfacing with these sensors and retrieving data for your applications.

In this module, we will introduce SPI and cover its basic concepts and operations. You will learn to implement SPI communication between two Arduino Unos and analyze the data using a logic analyzer. Additionally, we’ll demonstrate how to transmit DHT22 sensor values over SPI for streamlined communication in your projects.

In this module, we will cover I2C communication in detail, including its protocol, structure, and real-world applications. You will learn how to wire and interface sensors like the BH1750 and DHT20, analyze their data, and even expand your I2C network using multiplexers. Additionally, we’ll guide you through creating custom sketches for reading I2C addresses and setting up communication between multiple devices.

Closing chapter

In this final module, we will recap the main concepts and skills you've gained throughout the course. We will also offer a heartfelt thank you for your participation, along with encouragement for your continued exploration and learning in the field.
