The Raspberry Pi is a credit card-sized computer capable of running full-fledged Linux distributions such as Raspberry Pi OS, ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I ...

These multifaceted relay modules can reliably switch a multitude of small loads, decouple systems and multiply signals.

How the platform helps streamline the design process. The custom options offered.

Motorized faders are very cool, and you can find them in everything from expensive mixing desks to high-end video editing decks. If you want to build your own wireless motorized fader controls for ...

Abstract: This letter proposes a contention-based random access for air-to-ground communications, which is based on a slotted ALOHA protocol with a relay control scheme (RCS-ALOHA). In RCS-ALOHA, idle ...

In this paper, we consider the relay selection in wireless packetized predictive control (PPC) systems, where our goal is to select the relay nodes by jointly considering communication sub-system and ...

The Raspberry Pi uses 3.3V logic, while many relay modules require 5V logic to trigger reliably. To avoid using logic level shifters or risking unstable triggering, an Arduino Uno is used as a ...

A complete IoT system to control relays (lights/fans), monitor energy usage, and manage access via mobile app and admin panel.
