This video explains how resistors function and how Ohm’s Law defines the relationship between voltage, current, and resistance in electronic circuits. Resistors are passive components used to control ...

I get somewhat annoyed when I hear engineers who have some real-world experience or exposure casually dismiss a component, especially a passive one, as “simple.” It may be simple in concept or ...

Why get up close and personal with a resistor when you can tweak it from a distance? Remote variable resistors make analog circuit control easier, neater, and a lot more fun. Well, we are about to ...

Let’s say you want to blink an LED. You might grab an Arduino and run the Blink sketch, or you might lace up a few components ...

This article will help you build a simple Arduino-based DCC system. Growing up in the 1980s I was living the dream. I had an ...

More capable microcontrollers allow you to choose a pullup or pulldown resistor on the pin, and even select among possible values for the resistance and more. What matters is that we’ve got an ...

The electrical system of an automobile is likely the system understood the least by most Mopar owners, but compared to late-model vehicles the electrical and ignition system of a classic Chrysler ...

STMicroelectronics is aiming at industrial and telecom power supplies with half-bridge driver for GaN power transistors. With a maximum rail voltage of 220V, STDRIVEG211, as it will be known, is ...
