The explosive growth of the “Internet of Things” is changing our world and the rapid drop in price for typical IoT components is allowing people to innovate new designs and products at home. In this first class in the specialization you will learn the importance of IoT in society, the current components of typical IoT devices and trends for the future. IoT design considerations, constraints and interfacing between the physical world and your device will also be covered. You will also learn how to make design trade-offs between hardware and software. We'll also cover key components of networking to ensure that students understand how to connect their device to the Internet.
The Internet of Things (IoT) is a popular buzzword right now, but unlike many fads which have come and gone, the Internet of Things describes an important trend which is having lasting effects on society at large. The term itself, “Internet of Things”, is used to mean a variety of ideas, depending on the motivation and background of the speaker. This course will start by providing a definition of the term. We will talk about how various trends have enabled the Internet of Things, and how it changes the way design is performed. We will also discuss some of the ramifications that IoT is having on society today.
Introduction to the Internet of Things
The Internet of Things
The Basics of Sensors & Actuators
In Module 1, we introduced the concept of the Internet of Things at a high level, defining the term and outlining its implications. In this module we explore some of the details involved in the design and implementation of IoT devices. Unlike traditional computer-based systems, IoT devices are “embedded” within other devices in order to provide enhanced functionality without exposing the user to the complexities of a computer.
1.1: What Are Embedded Systems?
1.2: More on Embedded Systems
1.3: Generic Embedded Systems Structure
2.1: Components of Embedded Systems
2.2: More on Components of Embedded Systems
2.3: Sensors and Actuators (in the Lab)
3.1: Analog/Digital Conversion
3.2: Basic Equipment
Hardware and Software
IoT devices are implemented using both hardware and software components. Dedicated hardware components are used to implement the interface with the physical world, and to perform tasks which are more computationally complex. Microcontrollers are used to execute software that interprets inputs and controls the system. This module discusses the roles of both the hardware and software components in the system.

Networking and the Internet
An important aspect of the Internet of Things is that devices are networked in some way, and often connected to the Internet. Networking enables devices to communicate with other IoT devices and larger cloud-based servers. IoT devices can often be thought of as small parts of a much larger collective system which includes large servers based in the cloud. This module will introduce the basics of networking and the Internet protocol in particular. Eventually, most IoT devices are connected to the Internet, so understanding the protocols associated with the Internet is important to the design of IoT devices. We will also introduce the concept of a Mobile Ad Hoc Network, or MANET, which describes small, local networks of IoT devices.

Towards the end of the course, you will be working on a project where you will be implementing the techniques learnt during the course. You are expected to complete your project logically and successfully.
" I was able to stay with and understand Lazaro much better than my New Horizons experience. This is a great course. Thank you so much cybertron faculty .. really i appriciate u oll !!! "
" This is probably one of the best courses I have taken on Cybertron thank you! "
" one of the best instructors I have ran across. He makes the course fun but brings the material across in a way that you not only understand it but you remember it! Thanx a lot cybertron faculty .......!!! "
