Learn how to repurpose your spare ESP32 boards into cost-effective presence detection sensors using the Tommy Sense ...

A clock is by its very nature a device for measuring time, and thus it moves forward at a constant rate. But how about in a ...

If you want to get around Monaco, a map — digital or otherwise — is probably the best way to navigate. But if you just want ...

Arduino has certainly made its mark in the world of DIY electronics, providing an accessible platform for a wide range of creative and interactive projects. Known for its user-friendly hardware and ...

When you think of Arduino projects, your mind likely goes straight to RFID door locks, weather sensors, or automated plant watering systems. While these are undeniably pretty cool projects, you might ...

Measuring the speed of a rotating object is a common requirement. Knowing the speed of table and ceiling fans, as well as kitchen appliances such as mixers and grinders, can often be useful. However, ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

This project implements a smart traffic signal system using Arduino UNO, ultrasonic distance sensors, and LED signals. The system controls traffic signals at a junction by dynamically adjusting the ...

Photoelectric sensors detect objects and surface changes using variations in optical properties. Each sensor includes a light emitter and a receiver, with most relying on infrared light. In optical ...

The number and creativity of side channel attacks have increased dramatically in recent years. Of particular interest are attacks leveraging power line communication to 1) gather information on power ...
