Potentiometer Panel-Mount 1K - Linear Audio Pot solid state relay Do I need a separatePotentiometers are useful in projects that require analog signal calibration. They change resistance depending on how much you adjust the knob, which you can then read with a microcontroller device such as the Arduino to trigger your desired output. This particular potentiometer varies the resistance from ~0 to 1000. The knob is easy to turn, but not that it will shift on its own. The legs are 0. 1" apart perfect for breadboard prototyping.
