Measuring the speed of a rotating object is a common requirement. Knowing the speed of table and ceiling fans, as well as ...

Abstract: This article presents a novel configuration of the eddy current speed sensor to measure the rotating speed of iron rods and shafts up to 3000 r/min. The proposed eddy current speed sensor ...

With the increasing demand for automation and remote operation, controlling electrical devices without the need for physical access has become an important area of development in modern engineering.

Advances in embedded systems and sensors have enabled efficient, intelligent surveillance solutions that improve safety and control in transportation and automation applications. The system presented ...

Variable reluctance (VR) sensors transform mechanical motion into electrical signals by exploiting changes in magnetic flux. As a ferromagnetic target moves past the sensor’s pole piece, the ...

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 ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

Most modern vehicles come with two transmission speed sensors, which are responsible for monitoring the input and output shaft speeds of the transmission. These sensors send information to your car's ...

Sometimes, the factory speedometer isn’t an option. Maybe you’re trying different wheel and tire combinations that throw off calibration. Maybe the gauge cluster finally gave up the ghost. Or maybe ...

White House responds to Spain closing airspace to US military Video: Man tries pushing person in front of train Elon Musk is escalating his feud with a Delaware judge over a 'heart' on a LinkedIn post ...

We love Arduino here at Hackaday; they’ve probably done more to make embedded programming accessible to more people than anything else in the history of the field. One thing the Arduino ecosystem is ...
