Before we begin, first things first.
IoT (Internet of Things) is a huge network like a spider web where the smart devices transfer data between each other to perform a task. Thus, it performs a machine to machine interaction, however, the involvement of humans is very less in this process. Internet of Things (IoT) can interface gadgets inserted in different platforms to the internet. It extends the connectivity to a wide range of devices through the internet apart from Laptop, Mobile Phones, Desktop, and Smart Phones. When gadgets can speak to themselves, they can be controlled from anyplace. The network at that point enables us to catch more information from more places, ensuring more methods for expanding efficiency and improving safety.
IoT is considered as Next Digital Revolution by technology experts. IoT finds application in two major sectors, Industrial and Consumer segments. IoT is utilized for energy management and production line monitoring in the Industrial segment. Home automation is a major application where IoT is implemented at consumer level. IoT has developed tremendously, now it consists of more than 12 billion connected gadgets and as of indicated by specialists, it will increase to 50 billion before the end of 2020.

Some of the distinct features of Arduino which makes it an effective platform to build IoT Projects:
Raspberry Pi is a miniature sized computer which works similar to your desktop when plugged into a monitor or TV. Raspberry Pi uses SoC (System on Chip), SoC is a microchip which integrates CPU, Wi-Fi, Bluetooth, GPU in a single chip. As everything is integrated on a single circuit it consumes less power and improves performance also.
It is most suitable for hobbyists and enthusiasts to develop cool projects by which they can improve their skills in programming and understanding of hardware. Since Raspberry Pi is having an integrated Wi-Fi and Bluetooth module through which you can transfer and receive data from different sensors and devices, it is more preferable for building IoT projects. It can run a large group of operating systems too such as Windows 10, Android, Raspbian, etc. Raspberry Pi comes in different models like Raspberry Pi 3, Raspberry Pi zero, Raspberry Pi 4, etc. Among these models, Raspberry Pi 3 is the latest and widely used one.
