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 ...

An automatic toll gate system using Arduino revolutionises traditional toll collection by eliminating manual intervention. The “automatic toll gate system project” demonstrates how simple sensors and ...

Abstract: This paper is aimed to introduce a more flexible approach to installations using Arduino and interlock Sensors with different changeable modules.

To capture an instant on film or sensor with a camera, you usually need a fast shutter. But alternately a flash can be triggered with the scene in the dark and the shutter wide open. It’s this latter ...

The prototype of sensor that uses sound waves to generate electrical signalsAstrid Robertsson / ETH Zurich A new mechanical sensor developed by researchers at ETH Zurich is powered only by sound. It ...

A new mechanical sensor developed by researchers at ETH Zurich is powered only by sound. It could pave the way for ending the usage of disposable batteries in a wide range of devices. Interestingly, ...

A new mechanical sensor developed by a team led by Marc Serra-Garcia and Johan Robertsson harnesses sound vibrations to power itself, eliminating the need for batteries. This versatile and ...

Researchers are developing a new type of sensor that reacts to certain sound waves, causing it to vibrate. The sensor is a metamaterial that acquires its special properties through the structuring of ...

Researchers have developed a battery-free sensor that reacts to sound waves, such as particular spoken words, producing enough vibrational energy to power an electronic device. The novel sensor would ...
