[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. The ...

Efficient traffic management in urban areas remains a significant challenge as vehicle density grows and infrastructure struggles to keep pace. Conventional ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

An Arduino is a microcontroller — a single board designed to control something and perform a specific task. Unlike a ...

Every robotics project out there, it seems, needs a way to detect if it’s smashing into a wall repeatedly, acting like the brainless automaton it actually is. The Roomba has wall sensors, just about ...

This post is a review of the popular waterproof ultrasonic sensor JSN-SR04T. I hope this will serve as a backdrop for some interesting ultrasonic distance sensor experiments and projects. A number of ...

Diving into the world of DIY electronics can be quite daunting and overwhelming. There's the matter of picking the right components to use, learning the hand tools, and understanding the software.
