It happened when I was tidying up my desk drawer because I couldn't find something I was looking for. I found a small glass tube that I had bought a long time ago and forgotten about. I only had a ...

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 ...

The HX710(A/B) is a precision 24-bit analog-to-digital converter (ADC) with built-in temperature sensor (HX710A) or DVDD, AVDD voltage difference detection (HX710B). It’s designed for weigh scales and ...

It relies on an Arduino-based microcontroller to track the sun, linear drives, and a gyroscope feedback loop. Researchers at the Indian Institute of Technology, Madras (IIT-M) developed a low-cost ...

To avoid road accidents due to alcohol consumption, an innovative prototype, “Alcohol Proof Smart Vehicle”, has been developed, where the vehicle will not start if the driver is drunk. As per the ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

From a simple electronic toothbrush to complicated robotics systems, DC motors are present everywhere. In most of our previous Arduino projects, we have used these DC motors as actuators and ...

The following project is an update of Gary D. Patterson’s “Simplified CTC signals” in the July 1988 issue of MR. Bringing the project up to date was a large endeavour. The block control project now ...

Can you chip in? This year we’ve reached an extraordinary milestone: 1 trillion web pages preserved on the Wayback Machine. This makes us the largest public repository of internet history ever ...
