After a brief break, I found myself revisiting latching relays—not just as components, but as puzzles waiting to be solved.

Embedr is an AI-powered Arduino-like IDE designed to simplify development for Arduino-compatible microcontrollers. It looks ...

Use Arduino to handle sensor input and relay control. Pi runs a Python Flask server with a simple UI to toggle GPIO pins via serial commands sent to the Arduino. Use cron jobs on Linux to schedule ...

This project uses an Arduino microcontroller to find and locate internal cable line faults. In many environments, electrical cables are buried rather than overhead, making it difficult to locate ...

Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

The code includes two Arduino libraries: one for the servo and another for the ultrasonic sensors. The main code is a simple 14-line piece with a simple if-else statement you can readily modify.

It takes a handful of LED arrays with an integrated driver, an Arduino Nano, a real-time clock module, and a voltage regulator. Continue reading “Minimal Arduino Clock”→ ...

Or just use a MOSFET if the relay isn't very fussy. Or, use a combination of the Arduino driving something like the above timer relay, which itself will pull the 12V relay high if that's all it needs.

Insight into Arduino IoT shields. Their feature sets and applications. In the ever-expanding world of the Internet of Things (IoT), where connectivity is the name of the game, Arduino takes the ...

The Arduino controller can be programmed to output any of the standard 12 musical notes associated with the input. Although a simple piano may not sound like an exciting project, once you get the ...

Driving instructors and learners raised over £1,000 for Children in Need in memory of a super-fundraiser who sadly died earlier this year. The Big Learner Relay was started by Lou Walsh 10 years ...
