How to Learn IoT Quickly: A Guide for Beginners
With the rapid growth of the Internet of Things (IoT), it's essential to understand the core technologies and how to integrate them effectively. This guide is designed to help beginners quickly learn the essentials of IoT, focusing on firmware, hardware, and the web while setting realistic expectations for their learning journey.
Understanding the Basics of IoT
Internet of Things (IoT) is a broad term umbrellaing numerous underlying technologies. As an engineer, it's crucial to specialize rather than striving to be a 'superman' with extensive knowledge. Instead, focus on becoming an expert in your field, understanding the basics of related fields.
Firmware
Firmware is the backbone of IoT systems, operating directly on hardware. To effectively learn IoT, a programming background is essential. Specifically, C and C are highly recommended, as they allow you to work at the bit level, crucial for embedded Linux and microcontroller development.
For beginners, understanding the basics of low-level coding is important. You may choose to work on higher levels using existing libraries, but mastering the fundamentals is vital. Common tasks in firmware development include writing USB or other peripheral drivers in C, integrating sensors, and ensuring data is pushed to the cloud via communication options.
For learning resources, consider starting with:

Hardware is a critical component of IoT. As a hardware engineer, you should have a solid understanding of basic electronics, including resistors, capacitors, diodes, multiplexers, voltage regulators, H-bridges, op-amps, and ICs. Being comfortable with reading through documentation, such as 100-200 page datasheets, is essential.
For initial tasks, you might be testing and reviewing existing hardware components. As you progress, you may need to develop new hardware systems to perform specific tasks, such as collecting data from air quality sensors and pushing the data to the cloud.
Knowledge of schematic development using tools such as Eagle, Pro KiCad, or Altium or Fritzing is crucial. Understanding board-level design, including PCB manufacturing, and DFM (Design for Manufacturing) is also important, especially if you are involved in production.
IoT Ecosystem and Future Trends
To stay current and effective in the IoT domain, you should familiarize yourself with sensors and various communication options. Understanding which sensors to use in different scenarios and what communication protocols are most appropriate for each situation is key.
With the integration of AI and Machine Learning (ML), you should explore how these technologies can enhance your IoT projects and career progression.
Conclusion
IoT is a vast field with multiple avenues to explore. By focusing on firmware, hardware, and the web, you can build a solid foundation in IoT. Remember, becoming an expert in one area is more beneficial than attempting to master everything superficially.
