Sure, countless microcontroller development boards featuring a USB connection have made it to the Projects and Tutorials pages of Electroschematics. Although these days it really is easy to build your ...

Planning another Arduino build? If you’re just doing something simple like switching a relay or powering a LED, you might want to think about the Digispark. It’s a very small ATtiny-based Arduino ...

This article describes how I have set up a simple “door-sentry” at home. The door-open detector is designed to alert you to an unauthorized entry in a confined area. It uses a little ATtiny85 ...
