What is Internet of Things (IoT)? [Dev Concepts #24]

In this video of the series Dev Concepts, we take a look at Internet of Things (IoT) and concepts like embedded systems, microcontrollers, Arduino and ESP32.

With this tutorial episode, we take a closer look at the Internet of Things. IoT is a system that provides machines to transfer data over a network without the need for human-to-computer interaction. The term “thing“ is an object that we can assign to an Internet Protocol (IP) address and transfer data over a network.

IoT helps people gain complete control over their lives. It provides us with smart devices and automated homes. It is essential for businesses by providing a real-time look into how their systems work. It delivers insights into everything from the performance of machines to supply chain and logistic operations.

  • make more useful business decisions
  • improve employee productivity
  • generate better revenue
  • monitor business processes

As a programmer, it is crucial to consider IoT when choosing a programming language to learn. C is generally considered the best language for embedded IoT. C++ is the most common choice for complex Linux implementations. Python is well suited for data-intensive applications.

It allows people to access information from anywhere at any time. What is more, IoT transfers data packets over a connected network by saving time and money. On the other hand, as the number of devices increases, the potential of someone stealing the information also increases. If there is a bug in the system, every connected device will also become corrupted.

The embedded system software can be as simple as lighting controls running using an 8-bit microcontroller. It can also be complicated software  process control systems, airplanes etc. A microcontroller is a compact integrated circuit designed to govern a specific operation in an embedded system.

Recent advancements in IoT have drawn the attention of researchers and developers worldwide. As the number of connected devices continues to rise, our environments will fill with smart products. Developers around the world learn new languages to get the skills needed to run with the current changing world.
