This Design Idea describes an analog voltage that controls a digital potentiometer through the device’s I 2 C interface. An ADC in the Microchip PIC12F683 microcontroller converts the analog voltage ...

In the last video I demonstrated a Universal Active Filter that I could adjust with a dual-gang potentiometer, here I replace the potentiometer with a processor controlled solid-state potentiometer.

In many system applications, it becomes necessary to adjust a switched-mode power supply (SMPS) output voltage within narrow limits in order to remove tolerances and drops in the power path, verify ...

This file type includes high-resolution graphics and schematics when applicable. A common project requirement is to have an adjustable voltage regulator programmed to deliver a specific dc output.

Designers and procurement engineers requiring a finely tuned analog output controlled by a digital input have two options: digital potentiometers and digital-to-analog converters (DACs). Both use ...

Potentiometers, or variable resistors, are a standard component that we take for granted. If it says “10k log” on a volume pot, than we fit and forget. But if like [Ben Holmes] you are modelling ...

The newer a piece of farm equipment, the more likely some aspect of it needs to be calibrated, and sometimes re-calibrated, for it to work correctly. In case. you’ve ever wondered, here’s what ...

Potentiometers, sometimes called “pots,” are used frequently on modern farm equipment. In simple terms, potentiometers connect to a shaft or linkage that in turn is connected to some part of the ...
