Arduino Nano 33 IoT - Getting Started

Get started with PlatformIO, a great alternative to the Arduino IDE. Examples with Arduino, ESP32 & XIAO microcontrollers.

Today we are going to be programming microcontrollers with PlatformIO, a development environment with many advantages over the Arduino IDE.

I’ll show you how to install PlatformIO under Visual Studio Code (VS Code), a free programming environment from Microsoft (yes, Microsoft also makes free software!). Full instructions for Linux, Mac OS X, and MS Windows.

After we add the PlatformIO plugin to VS Code I’ll show you examples of using it with an Arduino Uno, an ESP32 development module, and a Seeeduino XIAO. You’ll quickly see the advantages of using this amazing programming environment.

I’ll also show you how to use the PlatformIO Library Manager, and how it differs from using libraries with the Arduino IDE. To do this we’ll also build a dual servo motor controller with an LCD display.

Everything around us has become smart, like smart infrastructures, smart cities, autonomous vehicles, to name a few. The innovation of smart devices makes it possible to achieve these heights in science and technology. But, data is vulnerable, there is a risk of attack by cybercriminals. To get started, let’s know about IoT devices.

What are IoT devices?

The Internet Of Things(IoT) is a system that interrelates computer devices like sensors, software, and actuators, digital machines, etc. They are linked together with particular objects that work through the internet and transfer data over devices without humans interference.

Famous examples are Amazon Alexa, Apple SIRI, Interconnected baby monitors, video doorbells, and smart thermostats.

How could your IoT devices be vulnerable?

When technologies grow and evolve, risks are also on the high stakes. Ransomware attacks are on the continuous increase; securing data has become the top priority.

When you think your smart home won’t fudge a thing against cybercriminals, you should also know that they are vulnerable. When cybercriminals access our smart voice speakers like Amazon Alexa or Apple Siri, it becomes easy for them to steal your data.

Cybersecurity report 2020 says popular hacking forums expose 770 million email addresses and 21 million unique passwords, 620 million accounts have been compromised from 16 hacked websites.

The attacks are likely to increase every year. To help you secure your data of IoT devices, here are some best tips you can implement.

Tips to secure your IoT devices

1. Change Default Router Name

Your router has the default name of make and model. When we stick with the manufacturer name, attackers can quickly identify our make and model. So give the router name different from your addresses, without giving away personal information.

2. Know your connected network and connected devices

If your devices are connected to the internet, these connections are vulnerable to cyber attacks when your devices don’t have the proper security. Almost every web interface is equipped with multiple devices, so it’s hard to track the device. But, it’s crucial to stay aware of them.

3. Change default usernames and passwords

When we use the default usernames and passwords, it is attackable. Because the cybercriminals possibly know the default passwords come with IoT devices. So use strong passwords to access our IoT devices.

4. Manage strong, Unique passwords for your IoT devices and accounts

Use strong or unique passwords that are easily assumed, such as ‘123456’ or ‘password1234’ to protect your accounts. Give strong and complex passwords formed by combinations of alphabets, numeric, and not easily bypassed symbols.

Also, change passwords for multiple accounts and change them regularly to avoid attacks. We can also set several attempts to wrong passwords to set locking the account to safeguard from the hackers.

5. Do not use Public WI-FI Networks

Are you try to keep an eye on your IoT devices through your mobile devices in different locations. I recommend you not to use the public WI-FI network to access them. Because they are easily accessible through for everyone, you are still in a hurry to access, use VPN that gives them protection against cyber-attacks, giving them privacy and security features, for example, using Express VPN.

6. Establish firewalls to discover the vulnerabilities

There are software and firewalls like intrusion detection system/intrusion prevention system in the market. This will be useful to screen and analyze the wire traffic of a network. You can identify the security weakness by the firewall scanners within the network structure. Use these firewalls to get rid of unwanted security issues and vulnerabilities.

7. Reconfigure your device settings

Every smart device comes with the insecure default settings, and sometimes we are not able to change these default settings configurations. These conditions need to be assessed and need to reconfigure the default settings.

8. Authenticate the IoT applications

Nowadays, every smart app offers authentication to secure the accounts. There are many types of authentication methods like single-factor authentication, two-step authentication, and multi-factor authentication. Use any one of these to send a one time password (OTP) to verify the user who logs in the smart device to keep our accounts from falling into the wrong hands.

9. Update the device software up to date

Every smart device manufacturer releases updates to fix bugs in their software. These security patches help us to improve our protection of the device. Also, update the software on the smartphone, which we are used to monitoring the IoT devices to avoid vulnerabilities.

10. Track the smartphones and keep them safe

When we connect the smart home to the smartphone and control them via smartphone, you need to keep them safe. If you miss the phone almost, every personal information is at risk to the cybercriminals. But sometimes it happens by accident, makes sure that you can clear all the data remotely.

However, securing smart devices is essential in the world of data. There are still cybercriminals bypassing the securities. So make sure to do the safety measures to avoid our accounts falling out into the wrong hands. I hope these steps will help you all to secure your IoT devices.

If you have any, feel free to share them in the comments! I’d love to know them.

Automated lawn irrigation with some valves and an Arduino Nano 33 IoT

There have been plenty of projects designed to automate lawn irrigation, however these normally refer to systems that open a single valve and turn on the sprinklers — all the sprinklers — at one time. Due to an irregularly shaped yard and a limited water supply, Sebastian Staacks wanted a bit more granular control.

Staacks’ setup consists of a half dozen Gardena valves, which are housed in underground boxes, while the brains and power supply are screwed to a wooden board on a wall in his garage. An Arduino Nano 33 IoT is employed to activate the sprinklers in six zones with an eight-channel relay bank. Relay channels 1 to 6 correspond to the valves controlling the sprinkler groups, the seventh is used for the main valve, and the eighth is saved for a “bonus” function that may be disclosed later.

Arduino Security Primer

At Arduino, we are hard at work to keep improving the security of our hardware and software products, and we would like to run you through how our IoT Cloud service works.

The Arduino IoT Cloud‘s security is based on three key elements:

  • The open-source library ArduinoBearSSL for implementing TLS protocol on Arduino boards;
  • A hardware secure element (Microchip ATECCX08A) to guarantee authenticity and confidentiality during communication;
  • A device certificate provisioning process to allow client authentication during MQTT sessions.

ArduinoBearSSL

In the past, it has been challenging to create a complete SSL/TLS library implementation on embedded (constrained) devices with very limited resources.

An Arduino MKR WiFi 1010, for instance, only has 32KB of RAM while the standard SSL/TLS protocol implementations were designed for more powerful devices with ~256MB of RAM.

As of today, a lot of embedded devices still do not properly implement the full SSL/TLS stack and fail to implement good security because they misuse or strip functionalities from the library, e.g. we found out that a lot of off-brand boards use code that does not actually validate the server’s certificate, making them an easy target for server impersonation and man-in-the-middle attacks.

Security is paramount to us, and we do not want to make compromises in this regard when it comes to our offering in both hardware and software. We are therefore always looking at “safe by default” settings and implementations.

Particularly in the IoT era, operating without specific security measures in place puts customers and their data at risk.

This is why we wanted to make sure the security standards adopted nowadays in high-performance settings are ported to microcontrollers (MCUs) and embedded devices.

Back in 2017, while looking at different SSL/TLS libraries supporting TLS 1.2 and modern cryptography (something that could work with very little RAM/ROM footprint, have no OS dependency, and be compatible with the embedded C world), we decided to give BearSSL a try.

BearSSL: What is it?

BearSSL provides an implementation of the SSL/TLS protocol (RFC 5246) written in C and developed by Thomas Pornin.

Optimized for constrained devices, BearSSL aims at small code footprint and low RAM usage. As per its guiding rules, it tries to find a reasonable trade-off between several partly conflicting goals:

  • Security: defaults should be robust and using patently insecure algorithms or protocols should be made difficult in the API, or simply not possible;
  • Interoperability with existing SSL/TLS servers;
  • Allowing lightweight algorithms for CPU-challenged platforms;
  • Be extensible with strong and efficient implementations on big systems where code footprint is less important.
