Therefore the potentiometers that are used in audio are approximating a logarithmic curve. I am providing different VolumeControl implementations which try to represent different yield curves, so that ...

Potentiometer with Arduino Overview This project demonstrates how to control the brightness of an LED using a potentiometer (analog sensor) with an Arduino. The potentiometer’s value is read by the ...

All of this makes one a particularly good choice for a volume knob or indeed any other large rotational control, so much so that we’re surprised it hasn’t become a more frequent occurrence.

The 2.2-mF capacitor at the control wiper forces all digital potentiometers to reset to their zero position on power up, ensuring that all pots start at the same position.

Components Required to Build the Arduino DC Motor Speed Controller Listed below are the required components to build the Arduino DC Motor Speed Controller: Arduino UNO - x1 IRLZ44N - x1 1k Ohm ...

The circuit uses three CAT5113P-10 digital potentiometers from Catalyst Semiconductor (see the figure). These pots have control lines connected in parallel as well as isolated resistor elements ...
