IoT Environment

An IoT system consists of many things, keeping the IoT layer model aside, there are several things and protocols that need a special mention, these are the things that make a basic IoT environment, these protocols are famous in the developer community and if one must learn about IoT they need to have a good understanding of these protocols. So we’re gonna look at some of these protocols, and understand their roles and advantages over each other. Additionally, we’re going to cover some basic aspects of IoT hardware as well.

I/O Interfaces

An IoT device contains many interfaces to communicate within and with other peripherals, this is done to increase processing and decrease the workload on a single processor, additionally, users interface IoT devices with other devices to increase work power and efficiency, this section contains the detailed description on those hardware and software interfaces, working on IoT you must be having knowledge of each and every interface that we use.
Serial Peripheral Interface (SPI)
This blog will introduce Serial Peripheral Interface (SPI), a synchronous serial communication interface specification used for short-distance communication.
Inter-Integrated Circuit(I2C) Interface
This blog is related to the I2C interface and learning the working of this interface.
UART interface in IoT EASY
In this blog, we'll study Universal Asynchronous Receiver/Transmitter (UART), a hardware device developed for transmitting and receiving data asynchronously.
CAN interface EASY
In this article, we will discuss what the CAN interface is, its importance in IoT, the physical layers of CAN, high speed CAN, and low speed CAN, and in the end, we will conclude the blog with the advantages and disadvantages of CAN.

IoT Hardware

As we’ve seen in the sections earlier, IoT covers both Hardware as well as software, both go hand in hand for a smart device to work. So in this section, we’re going to cover the most important parts of the IoT physical layer which are sensors and Actuators. These are the devices that actually come in contact with the physical environment. Sensors and Actuators are everywhere around us, in every smart device you’ll see at least 2-3 sensors or actuators, and in this section, we’re going to cover the most used sensors while building an IoT project.
Central Processing Unit (CPU) EASY
This blog talks about the Central processing unit (CPU) and its components.
Difference between BJT and Mosfet
