Mastering IoT: A Comprehensive Guide for Rapid Learning
I haven’t written an answer related to IoT in a while, but I am facing a similar problem of structured course content on YouTube and other online materials. This guide is my attempt to provide a structured path for learning IoT, focusing on firmware and hardware aspects. Whether you are a beginner or an intermediate learner, this article will help you navigate the complex world of IoT.
Introduction to IoT
IoT, or the Internet of Things, is an umbrella term that encompasses a wide range of underlying technologies. As an engineer, the goal is not to be a full-stack IoT developer. Instead, companies seek individuals who are experts in their respective fields, contributing to a structured process. While it’s essential to have a basic understanding of all related fields, it’s crucial to specialize in one area. This article will guide you through the process of mastering firmware and hardware aspects of IoT.
Firmware
Firmware is a critical component of IoT systems. If you have a programming background, start with C or Cplus;plus;. C and Cplus;plus; are preferred for low-level coding, especially in embedded systems where you work at the bit level. You can decide to work in a higher level using existing libraries or writing your own libraries. This could involve writing USB or other peripheral drivers, integrating sensors with microcontrollers, or collecting data and pushing it to the cloud via communication options. You should be comfortable with bit manipulations. Commonly used compilers include Arduino AVR Studio, MPLab, and Keil. While Keil is still in use, it's not the only option. Refer to this guide for more details on Arduino AVR Studio.

Hardware is a significant aspect of IoT development. As a hardware engineer, you should have a basic understanding of electronics, including resistors, capacitors, diodes, multiplexers, voltage regulators, H-bridges, op-amps, and ICs. Developers are expected to either develop a new hardware system for a specific task or test and review existing systems. Start with basic tasks like testing and reviewing existing sheets. As you progress, you will be required to develop new hardware systems, which can be challenging and require deep expertise. Tools like Eagle, Pro KiCad, Altium, or Fritzing will help you develop schematics. Microcontroller-based schematics are easier, but as you move on to processors, the complexity increases.

IoT is a vast and evolving field. By focusing on firmware and hardware, you can build a solid foundation. Firmware involves low-level programming and bit manipulations, while hardware requires deep knowledge of electronics and circuit design. As you progress, pivot towards more complex tasks and seek opportunities to specialize in your area of interest. This structured approach will help you become an expert in the field of IoT.
