Course Description

Welcome to the video course "Analysis and use of UART, I2C, OneWire, SPI and non-standard protocols in the Arduino/ESP environment"!

In this course we dive deep into the world of communication protocols and show you how to use them effectively with Arduino and ESP microcontrollers.

This course is ideal for Arduino and ESP enthusiasts who want to expand their understanding of communication protocols to create complex projects. Whether you are an experienced developer or a beginner, this course will provide you with valuable knowledge and practical applications.

This is not a theory course. We will jump straight into practical implementation and analyse and evaluate the protocols with a logic analyser.

In the course of the course, we will mainly deal with the most important communication protocols in the Arduino environment:

  • UART

  • I2C

  • OneWire

  • SPI

We will also look at non-standard protocols that are often used in special applications. You will learn how to identify, analyse and integrate these protocols into your Arduino and ESP projects.

After the introductory chapter, we can are able to handle bit operators so that we can do our own evaluations and libraries at bit level.

We will evaluate a light sensor (BH1750), DHT20 and DHT11 as well as an Ikea air quality sensor ourselves, without any external libraries.

In this video course we will use practical examples and demonstrations to teach you how to use these protocols. You will learn how to set up serial communication between different microcontrollers, transfer data, read sensors. We will also cover common challenges and troubleshooting that can occur when using these protocols.

By the end of the course you will have a solid understanding of UART, I2C, OneWire, SPI and non-standard protocols. You will be able to use these protocols safely and effectively in your Arduino and ESP projects and significantly expand your skills as a developer.

no resources avaiable, plus Instructor is hard to follow along

SI, FUE UNA BUENA ELECCION Y ME ASOMBRO MUCHO EL CONOCIMIENTO SOBRE EL TEMA DEL INSTRUCTOR

By Mario Gerasch on 3/3/2025

Manche Dinge müsste ich mir mehrmals anschauen um sie korrekt zu verstehen. Viele Dinge waren mir bekannt. Trotzdem noch vieles neuss gelernt. Super gemacht.

By Andrea Lombardo on 1/30/2025

Fantastic course. I learned a lot from it! the documentation is excelent and the booklet provided is an amazing add-on that will allow me in the future to review any topic that I may forget. Top class!!!

Avarage telling and some in efficient clearance

By Andrea Lini on 2/12/2024

Excellent course! Before starting this course I had some experience with Arduino but none with ESP8266 and ESP32. It was a bit of steep learning curve but I enjoyed the challenge. I will definitively be looking for more of Markus' courses.

By Brschucks Chucks on 1/15/2024

This is an excellent course. Markus makes short videos that are very clear to understand. The only thing I suggest improving is the SPI protocol, perhaps due to its complexity, there could be a dedicated course for the subject. I have already purchased other excellent courses from Markus, I recommend them!

By Rudi Majerle on 10/8/2023

Very clear and detailed explanations and examples that are useful in everyday work with Arduino modules.

By Vincenzo Caruso on 9/20/2023

Very good course with interesting trick and step by step instructions. Thanks.

By Micahel Small on 6/28/2023

A lot of knowledge coverd in this class. Thank you Sir!
