My son started playing competitive tennis at eight. What I didn't expect was that following his matches would be the hard part. At local courts and junior tournaments, scoreboards are surprisingly ...

It’s always nice to simulate a project before soldering a board together. Tools like QUCS run locally and work quite well for analog circuits, but can fall short with programmable logic. Tools like ...

A full-stack browser-based Arduino simulator built on top of avr8js and Wokwi web components. Write Arduino C++ code, design circuits visually, and watch them simulate in real time — all in the ...

Total mastery over the pinout and functionality of the PCA9306 for conversion of logic levels from 5V to 3.3V. A step-by-step interfacing diagram for the PCA9306 to Arduino UNO. Working example with ...

Let's jump on to learn about key features of the L298N Motor Driver, which plays a huge role in controlling heavy-load DC motors. It is based on a Dual H-Bridge design for controlling two DC motors ...

Jumperless V5 is a one-of-a-kind, programmable breadboard based on a Raspberry Pi RP2350B microcontroller that lets you skip the jumper wires and jump right into prototyping. It is described as “an ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

The first name on the list is Autodesk Eagle, an engineer-friendly tool that boasts a vast library of resources. It offers a full suite of PCB layouts, schematic editing tools, and collaborative ...

The following project is an update of Gary D. Patterson’s “Simplified CTC signals” in the July 1988 issue of MR. Bringing the project up to date was a large endeavour. The block control project now ...

Whether you're making the first steps in a new and exciting learning journey or you're on the verge of making a discovery that will revolutionize circuit design, having a test environment is paramount ...
