Sometimes it is useful to have a variable resistor that can be controlled via a microcontroller, even if the adjustment resolution is not very fine. Often, as few as 16 steps are adequate (e.g., for ...

Designers of instruments or control systems often find that component performance limits overall equipment performance in areas such as stability, frequency response, noise, and ESD. This is ...

Ben's Solid State A/V Switcher. Comes in any color you'd like as long as it's black. As you probably recall we recently had several articles on the Wii laptop which, of course, has Virtual Console ...

This project is also available at Instructables. Working on electronic projects at the workbench, whether prototyping with a circuit, powering a small desktop device, or simply testing a component, ...

A variable resistor that integrates a programmable, temperature-indexed look-up table can compensate for the temperature drift of a voltage regulator. In this case, the look-up table can change the ...

A potential divider, also known as a voltage divider, is a simple yet essential circuit used to reduce voltage to a desired level. It consists of two resistors connected in series close seriesA way of ...

If you’ve ever worked with guitar pedals or analog audio gear, you’ve probably realized the value of a resistor decade box. They substitute for a resistor in a circuit and let you quickly flick ...
