    Breadboard trim potentiometer – 10K

    These potentiometers are great for project prototyping. The three legs are spaced to fit perfectly in our range of solderless breadboards, giving each leg its own lane for hooking up to your microcontroller with jumper wires.

  • Potentiometer


    A potentiometer is a manually adjustable variable resistor with 3 terminals. Two of the terminals are connected to the opposite ends of a resistive element, and the third terminal connects to a sliding contact, called a wiper, moving over the resistive element. The potentiometer essentially functions as a variable resistance divider. The resistive element can be seen as two resistors in series (the total potentiometer resistance), where the wiper position determines the resistance ratio of the first resistor to the second resistor. If a reference voltage is applied across the end terminals, the position of the wiper determines the output voltage of the potentiometer.
