With a linear potentiometer, at one volume level you'll need to turn it further to increase/decrease the volume than when at a different level. The taper 2. Bend them so that they match potentiometer pins order and solder them. You can set up potentiometers to divide voltage in a non-linear manner, which can be very useful for audio applicationssince our ears don't hear changes in sound linearly. Answer (1 of 2): A potentiometer or "pot" used for volume control has an audio taper. Connections from the Rotary potentiometer to the Arduino: potentiometer GND pin Arduino GND pin. Potentiometer as a volume control. The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential (voltage); the component is an implementation of the same principle, hence its name. Voltage drop across R 2 = 50 can be found by voltage division rule, that is V R2 = 10 (50/200)= 2.5 V The potentiometer has three pins, but you don't need to use all three if you don't need them.

If you work closely with the design of audio equipment, you soon discover the negative impact that a pot can have on audio quality. You'll need the right kind of potentiometers, a way to connect that potentiometer, and finally a way to mount it into the cabinet. Potentiometer as a volume control . If the impedance of the pot is high relative to the speaker's input impedance, there will be more "drop" across the pot at low & mid volume-settings, so the volume will be lower. Because of its predictability, many people prefer a linear pot for their volume control. The treble loss when rolling back the volume (aka "volume vs. tone problem") The taper I imagine we''ve all experienced this problem - the volume control . AB Elektronik ABW1 Series 1W Wirewound potentiometer It converts rotary or linear motion from the operator into a change of resistance, and this change is (or can be) used to control anything from the volume of a hi-fi system to the direction of a huge container ship.
