When you’re prototyping a new project, sometimes all you need is a switch. The folks at oomlout were tired of constantly having to rewire things, so they built a universal switch box for the Arduino.

One part that I find myself using somewhat regularly in microcontroller-based experiments is the “USB power bank” that provides USB-standard 5-V DC output and offers some basic protection features.

So you've already outgrown Arduino's most beginner-friendly board, the Uno, and are looking to move on to bigger, more exciting projects. In that case, the Nano family might just be what you need.

An Arduino is a microcontroller — a single board designed to control something and perform a specific task. Unlike a ...

An Arduino can be used to test the life of any battery with less than 5 volts, Boxall says. So, for a quick way to see how much juice your AAA, AA, C, or D batteries have left, build this ...

The Arduino is a cheap, fun way to get into building your own electronics. It can also be daunting to get started. Here, we’ll show you how to get a start-to-finish Arduino primer with a killer ...

The big picture: If you don't know anything about electronics but have always wanted to learn and build your own IoT project, Arduino has the solution for you. The Plug and Make Kit is a comprehensive ...

We’ve all got calculators on our phones, in our web browsers, and even in the home “assistant” that’s listening in on your conversations all day on the off chance you blurt out a math question is can ...

After a major water leak flooded my home, I realized alerts alone weren’t sufficient—I needed automatic shutoff. This project combines a hacked Gröhe Guard system, an Arduino Nano, an ESP32, and the ...
