 # Embedded Systems Engineering Roadmap
 
-This roadmap is designed to assist beginners aspiring to build a career as an Embedded Engineer / Developer. To provide comprehensive guidance, the topics have been carefully selected based on current job requirements and organized according to my personal experience.
+This roadmap is designed to help beginners aspiring to build a career as an **Embedded Engineer/Developer**, as well as assist current practitioners in expanding their skills. 
 
-Becoming an embedded engineer requires a broad understanding of both software and hardware. If you are starting on this journey, you must be highly motivated and passionate to pursue this path. The field of embedded systems demands a solid understanding of hardware functionality. But, as the well-known saying goes, "Hardware is hard!". So, patience and passion are the essential qualities that will help you overcome the various challenges encountered along this journey.
+You should know that becoming an embedded engineer requires a broad understanding of both software and hardware. If you really want to pursue this career you must be highly motivated and passionate about it. As well as programming and software development skills, embedded systems demand a solid understanding of hardware functionality. However, as the well-known saying goes, "Hardware is hard!". So if you still know nothing about embedded systems, a hard yet exciting journey awaits you. But don't panic and be patient for the challenges you may encounter along this journey. By dedicating enough time and effort practicing and doing projects you will soon find yourself as a real embedded engineer! 😀

-## Roadmap
+## 🗺️ The Roadmap
 
 The roadmap is divided into three main sections: **SOFTWARE**, **HARDWARE**, and **SOFT SKILLS**.
 
-The hardware and software sections overlap in many embedded job roles. Different job titles, such as "Embedded Software Engineer / Developer," "Firmware Engineer / Developer," and "Embedded Linux Software Engineer / Developer," tend to focus more on software. On the other hand, job roles like "Embedded Hardware Engineer" and "Hardware Design Engineer" primarily focus on hardware. Additionally, there are positions like "Embedded Systems Engineer" that require a good understanding of both hardware and software. It's crucial to understand that each company in the embedded industry may have specific requirements for a job role, regardless of its title.

-With this in mind, the roadmap is designed to cover topics necessary for an "Embedded Systems Engineer" role. If you are aiming for an embedded software position, you should focus more on software skills in the roadmap. Conversely, if you are interested in an embedded hardware job, you should prioritize hardware skills.

If you are aiming for an embedded software position, you should focus more on software skills in the roadmap. Conversely, if you are interested in an embedded hardware job, you should prioritize hardware skills and put more time on learning electronics.
 
-In the embedded industry, all job roles require some soft skills, which cannot be acquired solely through reading or watching videos. Soft skills are developed through communication with others and facing various work challenges. Improving soft skills is not a one-size-fits-all approach. It varies depending on your individual characteristics and involves being aware of your own strengths and weaknesses. Enhancing these skills takes time and effort.
+Just like many other job roles, an embedded engineer requires some soft skills that cannot be acquired solely through reading or watching videos.

It will vary based on one's individual traits and requires self-awareness of your strengths and areas for growth. Enhancing these skills takes time and effort.
 
-**Remember that the emphasis on software or hardware skills may vary depending on the specific requirements of the company or job position.**

-## Learning Resources
+## 😕 Don't Know Where to Start!
 
-### ⭐️ Featured Material
+If you feel overwhelmed by the extensive list of topics in the roadmap, you're not alone. Before delving too deeply, let's ease into it with some simple starter projects. Learning embedded systems engineering takes time and effort. Don't get discouraged if you don't understand something right away. Keep practicing and you will eventually get there.
 
-#### 🔎 Searching is Your Super Power!
+### ⚒️ Projects
+
+Engaging in hands-on projects is the most effective approach to learning. Rather than solely relying on theoretical knowledge from books or articles, undertaking projects allows for practical learning experiences. Even a seemingly basic project has the potential to teach you more than aimless reading. You can refer to books, articles, and courses when faced with difficulties in understanding the problems in a real-world project.
+
+Don't try to build a complex project right away. Start with small, manageable projects to get your feet wet.

+### 🕹️ Arduino
+
+If you do not have any background in programming the embedded systems, Arduino boards and libraries are the best choice for you to start and learn the basics. Just keep in mind that most of the Arduino libraries are developed for learning purposes and are not optimized to be used in industry.
+
+Additionally, the [Arduino Core](https://github.com/arduino/ArduinoCore-API) takes care of most of the low-level operations and manipulation of registers that you, as an embedded engineer, should be able to handle yourself. If you want to become a professional embedded developer, you should be able to effectively use industry-standard APIs and SDKs provided and approved by microcontroller vendors. For example, CMSIS for ARM Cortex, STM32Cube for STM32, ESP-IDF for Espressif microcontrollers, etc.

 PlatformIO is not yet extensively adopted in industrial and large-scale projects, however, it is an excellent choice for individuals working on smaller projects. This is because it greatly reduces the need to install frameworks and setup build and debug tools, allowing you to concentrate on programming.

 ## History
 
-The idea of creating this roadmap came from [vazeri / Embedded-Engineering-RoadMap-2018](https://github.com/vazeri/Embedded-Engineering-RoadMap-2018) which was well designed but had some flaws and not updated for years.
-I took that idea, changed the structure of the roadmap and tried to improve it. The initial results can be accessed in [m3y54m / Embedded-Engineering-Roadmap-Archived](https://github.com/m3y54m/Embedded-Engineering-Roadmap-Archived) which is now archived. Early versions of the roadmap were created using [Balsamiq Wireframes](https://balsamiq.com) which is not suitable for these types of diagrams. So I decided to use Microsoft Visio instead and redrew the whole diagram.
+At first this was meant to be my personal reading list but as the list gradually became bigger and bigger, I wondered why not share it with others. So I did research on current job postings for embedded engineering roles, selecting the most frequent skills and including them on a roadmap. In order to make the roadmap more comprehensive I also added some basic skills and finally came up with what you see here.
