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.

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

With their cheap price tags, massive I/O provisions, and low power consumption, microcontrollers like the uber-popular Arduino family have diverse use cases, from simple automation projects to full-on ...

When it comes to performance, there's a world of difference between the Raspberry Pi and Arduino. The former, after all, is technically a fully functional computer that can run games, word processors, ...

This short project investigates using a power switch tail with the Arduino. The power switch tail allows a user to turn outlet run devices on and off with the Arduino. Therefore using this project as ...

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 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 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 ...

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 ...
