Potentiometer henceforth referred to as a pot, is a variable resistor.
It is an electrical component with three terminals (i.e. pins or legs): o
Mechanically speaking, pots are physically adjusted usually using your fingers.
Both rotational and linear pots are common.
f you want to control the speed of your electric motor, the position of your servo, LED brightness, filter cutoff on your synthesizer, gain on your guitar amp or thousands of other cool things in your own embedded system, a pot might just be the solution for you.
The potentiometer is a handy little component that you really should know how to use.
It’s used in circuits a lot, such as to control the volume of music equipment, control the brightness of a light, and much more.
If you’re not familiar with it, it can seem complicated to use in a circuit. But once you see how it’s built, you’ll quickly understand how it’s done.
What Is A Potentiometer?
It is like the resistor.
But while the resistance value of a resistor stays the same, you can change the resistance value of a potentiometer by turning it’s shaft.
It has three pins and the schematic symbol looks like this:
