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.

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, ...

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 ...

Here is the circuit of an Arduino-based Panic Alarm! The wiring is very simple so that even a novice can construct this interesting circuit without any difficulty. Arduino is a family of ...

Despite their similar sizes and affordable prices, microcontrollers and single-board computers have vastly different specifications and use cases. After all, MCUs are designed for circuitry, ...

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 ...
