Potentiometers are a ratiometric, variable resistor which allows you to control the flow of current using physical input, and they come in all kinds of shapes and sizes.
This 1K potentiometer is a two-in-one, good in a breadboard or with a panel. Its a fairly standard linear taper 1K ohm potentiometer, with a grippy shaft. Its smooth...

These are Adafruit's favorite trimpots, perfect for breadboarding and prototyping. They have a long grippy adjustment knob and with 0.1" spacing they plug into breadboards...

This slim and modern potentiometer is small and compact, yet looks good and has a nice feel. Adafruit hand selected the best knobs for your project in different sizes...
This plastic knob accepts a 6mm shaft and has a 15mm outer diameter. They simple press-fit onto a shaft. These are clear so that they can be used with our illuminated rotary encoders.
Here's a new addition to our rotary-potentiometer-knob family. This knob has a nice soft-touch feel with an arrow on it, and its much 'slimmer' than the skirted knob we have been using, so good for compact layouts.
These guys are like standard pots, but rather than moving in a circular direction, they move linearly, which is really handy for things like mixing consoles.
A simple slide potentiometer can go a long way. Rated at 10kOhm and 0.5W. Comes with solder tab connections. The taper profile for this slide can be found in the datasheet below labeled “0B”
A simple slide potentiometer can go a long way. Rated at 10KOhm and 0.1W. Comes with solder tab connections. The pot has an overall travel of 20mm and has two mounting holes on top.
A simple slide potentiometer can go a long way. Rated at 10KOhm and 0.1W. Comes with solder tab connections. The pot has an overall travel of 30mm and has two mounting holes on top.
Digital pots are nifty devices which communicate with a microcontroller digitally, and have a cascading resistor ladder which creates an analog path of resistance.
Potentiometers are incredibly useful, whether you’re controlling the volume on your stereo or the ‘mood lighting’ in your room. The problem with traditional potentiometers is the fact that your microcontroller doesn’t have an easy way to interface with them. Digital Potentiometers solve that problem by allowing you to control a voltage splitter with digital signals.
