Infineon has developed an Arduino shield to demonstrate the potential of its 24V Profet protected power switches. Called the Protected Switch Shield, it is also compatible with the firm’s own XMC ...

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 ...

Here is a simple general-purpose security alarm circuit built on the Arduino platform. It brings up an obtrusive alert signal when an intrusion/theft attempt is observed by its front-end sensor. In ...

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.
