The Internet is considered by many to have been one of the greatest technological advances of the 20th century. Here in the 21st century the Internet of Things (IoT) might well earn that title.

Currently in its infancy, the Internet of Things is a network of physical objects – computing devices, appliances, vehicles, sensors and even entire buildings that are interconnected through the Internet. Already devices like IP cameras and Nest thermostats allow us to control and monitor our homes remotely through our smartphones. Soon this technology will be combined with other technological advances such as self-driving cars and biometric clothing to allow capabilities that we can’t even dream of right now.

There are many ways that you can get started experimenting with the internet of things right now. Small microcomputers and microcontrollers like the Arduino and Raspberry Pi or dedicated IoT devices like the Intel Spark and Photon will allow you to build and design Internet of Things devices quickly and efficiently. Once you’re done you can use applications like If This Then That (IFTTT) to control your creations from anywhere in the world.

Control the world or water your plants – let’s get started and build some great devices for The Internet of Things!


Arduino Iot Cloud 2024 - Fundamentals

The Arduino IoT Cloud has had many exciting updates since we last examined it, so many that in 2024 it doesn't even look the same! With a wealth of boards to connect to, and new features like Triggers, it's time we took another look at the Arduino IoT Cloud.

Follow along for a detailed guide, suitable for makers of all levels!

Water Your Garden with IoT

Learn to use soil moisture sensors, both resistive and capacitive.

After calibrating our sensors, we will use them to build two projects. One of them is a soil moisture meter, the other is an automated watering system that uses the Arduino IoT Cloud.

Getting Started with the Arduino IoT Cloud

Today we will look at the Arduino IoT Cloud, an online application for building Internet of Things (IoT) devices.

I'll show you how to get an account set up, how to configure your workstation, and how to build your first "Thing".

The cloud was recently updated, so now even free plan users can work with the ESP32, and I'll show you how to do that as well.

Arduino Nano 33 IoT Board

Today we will look at the Arduino Nano 33 IoT board, an updated 32-bit version of the original Nano. This board combines WiFi, Bluetooth, an IMU, and a Real-Time Clock in a package identical to its older cousin.

We'll see how to set up the board with the Arduino IDE and how to use all of its features.

I'll be using this board in a few IoT projects, so it's a good idea to get familiar with it.

WiFi Stepper Motor Controller

The WiFi Stepper is exactly what its name would imply - a board that lets you control a stepper motor via WiFi. Its full-featured web-based interface gives you complete control of your motor, and it can support steppers of all sizes up to 85 volts at 10 amps!

Today I'll demonstrate how to use this versatile board. I'll hook it up, learn how to use it and even run a simple Bash script on a Raspberry Pi to demonstrate how to incorporate it in your programs.
