Cellular-enabled IoT is here — and it’s making long-range connectivity easier and more affordable than ever. Here’s Ubidots’ top 6 affordable cellular IoT hardware devices.  Continue reading “Top 6 affordable cellular IoT hardware devices”

WiDo IoT Node Review

We recently got a support ticket about the WiDo board from DF Robot. As it was the first request for this module, we immediately ordered a unit to get our hands on it.

After some minutes of playing with the board, we were positively impressed. Its Arduino form factor makes programming a breeze, and the fact that it integrates a WiFi module makes it very attractive for most IoT projects (no need for a WiFi shield).

Control an LED remotely with an Arduino and Ubidots

This tutorial shows some of the basic capabilities of an Arduino and it’s integration with Ubidots. After doing it, you’ll learn what an Arduino is, what it does and how you can set it up to turn an LED (or any other actuator) on and off from your Ubidots account. All you need to get started is an Arduino board and the official Arduino WiFi Shield.

What is Arduino?


Arduino is an open-source electronics platform based on easy-to-use hardware and software. The basic board can be connected to a series of devices to expand it’s possibilities; these devices are called “shields”. For this specific tutorial we will use the Arduino WiFi Shield.
