Introduction: Working With Potentiometers

About: I'm an Instructables success story! After relying on the site to DIY my way through art school, I was able to join the Instructables Design Studio in 2012. It's the best! Whe...

Potentiometers, or "pots" for short, are means of adding variable resistance control to your circuit. Each potentiometer is rated from 0 to the marked amount of Ohms on the potentiometer. In this instuctable, I am using a 1000 Ohm, or 1 Kilo Ohm, potentiometer. I demonstrated this property of the potentiometer by using a digital multimeter set to the Ohm symbol.

Potentiometers have three leads. By connecting a circuit to the outer two leads, the resistance of the potentiometer will match the  resistance marked on the potentiometer. It will behave like a normal resistor. When the circuit is connected to a center lead, and an outside lead, the potentiometer will behave like a variable resistor - turning the post of the potentiometer will increase (clockwise), or decrease (counter-clockwise) the resistance of the potentiometer.

    this really did help me understand potentiometers better. Thanks for posting

    thanks! simple and helpful :)

    cool I need to learn about potentieometers
