Arduino IoT Cloud For Busy People
Learn Arduino IoT Cloud to create IoT applications based on the Arduino MKR1010, the Arduino Nano 33 IoT, and the ESP32.
Course last updated in December 2022
This update contains a new lecture that covers the changes to the Arduino Cloud user interface introduced in the second half of 2022.
The Internet of Things is a term that describes systems that integrate sensors, processing, software and communications.
A typical Internet of Things application uses the Internet as the backbone for communications between microcontrollers, Cloud services, and smartphones.
The Arduino IoT Cloud is a development platform and infrastructure that makes it easy to create scalable Internet of Things application.
As a development platform, it offers the technology building blocks which we can use to build our application.
It also offers the infrastructure that supports the safe operation of our application.
Who is this course for?
This course is for anyone wanting to create secure and scalable IoT applications.
You can be a hobbyist working on a home automation project, or a student working on an assignment or a teacher setting up an IoT lab in the school maker space.
You could be the founder of a startup creating a prototype for an awesome business idea, or a business owner interested in using IoT to automate and optimise your business operations.
You could be an engineer, researching a technology solution for your employer.
The building blocks consist of the hardware that we can use to interface sensors and actuators with the Cloud infrastructure. Examples of this hardware are the Arduino boards that belong to the MKR family. These boards contain communications and encryption capabilities to ensure the safety of the application data.
The development platform also offers a programming editor that allows us to compose the program that runs on the Arduino boards, and a dashboard editor for creating dashboards that can display application data and provide interactivity with the IoT application.
What are the objectives of the course?
1. Understand the concept of the IoT on the Cloud.
2. Learn how to use the Arduino IoT Cloud development platform and infrastructure.
3. Learn about the Arduino IoT Cloud concepts of Things, Devices and Dashboards, using two types of Arduino boards and an ESP32 board, with a variety of sensors and actuators.
Of course, the dashboard editor allows us to design dashboards that work in web browsers and on smartphones. This means that we can access our IoT application from any connected device.
The Arduino IoT Cloud infrastructure is what supports you application during its operation. It is responsible for interacting with the devices (meaning, the Arduino or other compatible boards), the smartphone or web-based dashboards, and any external cloud services, like IFTTT or Zapier.
What are the knowledge prerequisites?
1. You should have working knowledge of the Arduino. If you don’t feel comfortable with this, please consider completing my course Arduino Step by Step Getting Started first.
2. You should have working knowledge of the ESP32. If you are note familiar with the ESP32 board, consider first completing at least the introductory sections of my course ESP32 For Busy People.
You, as the creator of the IoT application, can create secure and scalable IoT application by leveraging your existing knowledge of Arduino programming and simple electronics. You don’t need to know anything about encryption, communications, MQTT, Wifi, or how to program a smartphone or server-side application. The Arduino IoT Cloud platform and infrastructure obscures all that so that you can concentrate on building your application.
The objective of this course is to help you leverage your existing knowledge of Arduino programming and simple electronics so that you can build your first IoT application on the Arduino IoT Cloud.
Hardware & Software
To complete this course, you will need an Adruino board that is compatible with the Arduino IoT Cloud. In the course, I use an Arduino MKR1010, an Arduino Nano 33 IoT, and an ESP32.
You will also need a few common sensors and actuators, plus breadboards and wires.
