A common sight in ‘smart homes’, door sensors allow you to detect whether a door is closed or open, enabling the triggering ...

Arduino test code is run to see if the sensors are working properly, with built-in LED flashing when the sensor is triggered, and turning off when the sensor is released. The testing of the keys ...

Sometimes the simplest objects need some overthinking. This is exactly what [Chris Borge] realized when using his 3D scanner and finding that the included rotation table left quite a bit to be ...

The world of car diagnostics has changed a lot over the last 50 years. Back in the '70s and earlier, a mechanic's most valuable diagnostic tools were usually their eyes and ears. You could figure out ...

Designed by Nova Radio Labs in the US, the Novaduino Environmental Sensor Kit is an Arduino-programmable air quality and weather monitoring solution built around the company’s own Novaduino Display ...

Arduino is being acquired by Qualcomm subject to regulatory approval for an undisclosed sum. Qualcomm Arduino introduces a new UNO form factor board, the Arduino UNO Q, which features both a STM32 MCU ...

Abstract: An intensity-modulated active intracavity rotation angle sensor was demonstrated based on a simple balloon-type fiber. The sensor leverages macrobending-induced loss, modulated by torsional ...

Curious about how cadence sensors work and how to use them effectively? This hands-on guide breaks down the basics of cadence sensing—from the core principles behind pedal rotation tracking to ...
