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.

Rotary

Rotary potentiometers are commonly used in user interfaces to create intuitive, rotary control panels that have physical end points.

  3. Rotary Potentiometer - 10k Ohm, Logarithmic
    SKU: COM-09940 Brand: Sparkfun
    An adjustable potentiometer can open up many interesting user interfaces. Turn the pot and the resistance changes. Connect VCC to an outer pin, GND to the other, and the center pin will have a voltage that varies from 0 to VCC depending on the rotation of the pot. Hook the center pin to an ADC on a microcontroller and get a variable input from the user!

Trimpots

Trim pots operate exactly like a standard potentiometer, except they've got a super small form factor which is perfect for calibration work.

Knobs

A raw, metal pot doesn't look inviting, nor is it easy to turn, which is why every project using pots should have a matching set of control knobs.

Sliding

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.

Digital

Digital pots are nifty devices which communicate with a microcontroller digitally, and have a cascading resistor ladder which creates an analog path of resistance.

  1. Digital Potentiometer - 10K
    Rating:
    90% of 100
    SKU: COM-10613 Brand: Sparkfun
    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.
