Building Internet of Things projects with Arduino can be quite complicated: first, you need to find the right hardware & libraries for your project. Then, you need to find the right online service to send your data to. Finally, if you want to have some live graphical visualisation, you need to find or build an online dashboard for your project.

In this guide, we are going to build an Internet of Things dashboard using the Adafruit IO service. We will see that using Adafruit IO makes the process so much easier, as it will allow us to easily send data to the cloud from an Arduino board, and also easily building an Internet of Things dashboard just by dragging & dropping some elements.

As an example, we will connect several sensors to an Arduino Uno board, which will use the CC3000 WiFi chip to connect to the web. Then, we will send the measurement data to Adafruit IO & visualise it there in real-time, from anywhere in the world. Let's dive in!
