This is a simple and very effective project circuit which helps to control the speed of a DC motor using pwm and microcontroller. In many applications, it is important to control the speed of DC motor ...

Temperature-indicator and temperature-based products have generated wide interest. There are numerous applications for such devices with many possible solutions, each with its own advantages and ...

A few years ago, the default answer to almost any “tiny computer” project was a full single-board computer running Linux. That made sense, because you got drivers, packages, a real filesystem, and ...

In the early digital era, logic gates were made exclusively of transistors and discrete components. The obvious occupation of a large space and increased heat dissipation pushed technology to ...

In safety-critical applications, trouble-free operation is enormously important, especially for microcontrollers. By law or in companies from the automotive, health or production industry, there are ...

This simple 4093-based audio peak detector from December 2004 monitors music and turns on a small light when the sound gets ...
