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 ...

In this project, we are going to build something very simple project, a temperature controlled relay that is used to turn on a dc fan. You can actually change the DC Fan to other electrical devices ...

I'm happy to flag this one, a new volume of the Arduino Project Handbook. Volume 2 sees twenty-five more beginner-friendly electronics projects, revolving around the Atmel AVR-based Arduino Uno board.

Building radio receivers from scratch is still a popular project since it can be done largely with off-the-shelf discrete components and a wire long enough for the bands that the radio will receive.

[Fran’s] been working on her own version of the Arduino. She calls it CuteUino for obvious reasons. The size of the thing is pretty remarkable, fitting within the outline of an SD card. But that doesn ...
