This post is a fast guide for people who want to try to build an IoT project using IoT boards and Free cloud platform. When you enter the IoT world for the first time, the impact can be a little scary. There are so many topics included in the IoT world and different technologies. The IoT is a growing topic in the world and many big players are working on it. It is possible, anyway, experiment by yourself some IoT DIY projects. There are many different IoT definition pointing to several IoT aspects.

This guide wants to provide all the information you need before starting your IoT DIY project so that you can select the right IoT prototyping board according to the scenario where your IoT DIY project will work and the right IoT cloud platform. As we will see later, an IoT cloud platform plays an important role in IoT project because usually in an IoT project the prototyping board acquires data using sensors and send it to the IoT cloud platform.

What is Internet of things (IoT)?

If you are new to Internet of things (IoT), I report here a brief description. There isn’t only one simple description of IoT but there are several definitions taking into account different aspects. Generally speaking, IoT is the convergence between Wireless technologies, microcontrollers, services and Internet. The key factors of IoT are:

  • The thing
  • Internet

The first one can be any device that is able to connect to the network. A thing or device is a smartphone, a microcontroller, a smartphone, lamps, wearable devices, sensors and so on.

The Internet is the mean that connects the devices. So the first requirement is that all the devices must be able to connect to the network so that they can exchange data and information.

These devices through internet exchange information. Using sensors they can collect information about the world around them. These smart things send all this information to other devices or platforms that are able to store it. Every single “object” connected to the net can be the source or the destination of the information flow.  It could be the information source when uses sensors. At the same time,  it could be controlled remotely by other devices. From this point of view, the security aspect plays an important role: it is necessary to protect somehow the information. For this reason, security is a big issue.

So it is clear how IoT will impact our everyday life. There are some areas where IoT will have a great impact:

  • agriculture
  • energy
  • healthcare
  • transportation
  • logistics
  • supply chain

The basic concept that stands behind is:

IoT world is a smart network of “intelligent” electronic systems, called things, inter-connected that are able to send and receive data

There are several application fields:

  • Smart home
  • Smart cities
  • Wearable
  • Health
  • Connected car
  • Industrial applications

and so on. As you can realize, the application field is wide.

First steps with IoT boards

So what do you need to build IoT DIY project? You should buy a smart object that is able to connect to the internet. If not, you are not building an IoT project. These objects are IoT boards because you can use them to build your IoT DIY project. There are several dev boards available in the market with different specification. The first approach might be difficult to select the right one. In my opinion, there are two dev board families that should be considered at the beginning:

  • Arduino families
  • Raspberry families

Families because there is a different version of Arduino and Raspberry board. Arduino UNO is one of the most famous IoT dev board with Raspberry Pi 2. You can look at the available Arduino board. Raspberry has several dev boards too. While Raspberry has integrated ethernet connection and even WI-FI (in Raspberry Pi 3), Arduino doesn’t have it. In this case, you have to buy an expansion shield like an ethernet shield or wi-fi shield. Recently a new dev board is available called Arduino MKR1000 made for IoT project. I use Arduino Uno and Raspberry Pi 2 model B+and MKR1000 to build IoT project.

IoT prototyping board list

In this scenario, it is useful, to build your IoT DIY project, to have a list of IoT rapid prototyping boards (or development board). These boards play an important role. They are microcontrollers and microprocessors with chipsets to handle wireless connections. These development board with Cloud IoT platform enable a fast prototyping process.

Moreover, the spread of these IoT rapid prototyping boards is helped by the low price. Hobbyists and makers can use them in their IoT projects, without investing too much money. For this reason,  I think it is helpful to have a list of development boards ready to use in IoT projects before starting your IoT DIY project.

The main features are:

  • 5V (operating voltage)
  • 8bit
  • 16MHz

It has, moreover, analog and digital pins. The interesting aspect of this board is it can be expanded using shields. A shield is another board that can be plugged into Arduino Uno that adds new features like GSM, Ethernet connection, WIFI and so on. It is very simple to use and has an official IDE to develop applications (or sketch). There are, also, free and paid IDE that offers more features respect to the official one. Recently, it is possible to add to this board Arduino Yun shield. This shield is made for IoT project and extends the Arduino Uno board features.

Arduino MKR1000

Arduino MKR1000 is one of the latest board. MKR1000 has been designed for IoT projects. It supports natively WIFI connection and it is very easy to use. It is based on the Atmel ATSAMW25.

This post wanted to give you an overview of IoT ecosystem and how to start building IoT DIY project. There are infinite IoT DIY projects to develop, your fantasy is your limit. You can build IoT sensor based projects or you can control remotely Arduino with a smartphone.


  1. Gave me a good overview of several “unknown terms” I’ve been reading in different articles. And most importantly … Pi or Arduino

    • Arduino UNO is a dev board used to start with electronics and IoT projects. It is a micro controller and it has an IDE to develop application. Raspberry PI (different versions) is also a dev board but much more powerful than Arduino UNO. Raspberry has a OS called Raspbian (Linux like) or you can install other OS like Windows 10. It depends on the type of project you want to build. Both dev boards have a I/O pin that can be used to connect components like sensors, motors, shields and so on.

    • Do you mean a blinking led? If so you can buy Arduino Uno or MKR1000 or something like that. A led and if you buy Arduino UNO you need an ethernet shield of WIFI shield to connect it to the net. With MKR1000 you don’t have to buy the shield, it has WIFI module built-in.

  2. For an impressive, small dev board check out the Oak, built in wifi, particle connected and the size of a silver dollar.
