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, ...

This paper presents a methodology for the measurement of strain by means of strain-gauges, where the data acquisition is done by using an Arduino Uno board, due to the low-cost and the easy ...

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 ...

I'm trying to get block detection working on my HO scale model railroad. I found this page and liked the idea of using current transformers to detect the Digital Command Control signal inducing ...

Abstract: Underground power cables are essential for modern power distribution systems, ensuring reliable electricity supply in urban and rural areas. However, fault detection in these cables is ...

How to implement NEC protocol logic on a configurable mixed-signal IC. Discover ways to eliminate external components and reduce coding complexity. Configure up to nine custom commands using the ...

Of course, many different types of distance measuring sensors exist but not all sensors are the same. Each sensor has its own advantages and disadvantages. At its most basic level, a distance ...

Robert Sontheimer’s Book, ‘Arduino & Co – Measure, Control, and Hack,’ was recently published in English, following its success as a German book. The author takes a unique approach to developing some ...

The oceans represent 97% of all water on Earth and contain microscopic, drifting life, plankton, which drives global biogeochemical cycles. A major hurdle in assessing marine plankton is the planetary ...

The Pneumatron device measures gas diffusion kinetics in the xylem of plants. The device provides an easy, low-cost, and powerful tool for research on plant water relations and gas exchange. Here, we ...
