A range of Arduino-based projects is enabling automation in document handling, 3D scanning, smart home monitoring, biometric security, and home system control. These solutions use open-source hardware ...

PWM relays allow engineers to go beyond simple "on-off" control to realize significant power savings and reduced heat ...

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, ...

In 2026, Arduino has quietly revolutionized the DIY landscape, moving beyond basic blinking LEDs to become a powerhouse for home interior upgrades. The launch of the AI-powered Cloud Editor and the ...

Unlike an Arduino board that requires external components to be functional, a Raspberry Pi is a powerhouse by itself right out of the box. It is, after all, a computer. This means that by simply ...

What’s one to do with some nice little relays of questionable pinout, and prototyping board? How about a quietly clicky 4-bit ...

The concept of a 3D scanner can seem rather simple in theory: simply point a camera at the physical object you wish to scan in, rotate around the object to capture all angles and stitch it together ...

Abstract: This paper considers a multiuser single-relay wireless network, where the relay gets paid for helping users forward signals, and the users pay to receive the relay service. We study the ...

Abstract: Research on pilot-free communication has attracted significant attention for its potential to reduce pilot overhead and enhance spectral efficiency. Despite their competitive performance ...
