Shopping guide

Potentiometers can be used to regulate the intensity of sound in a player and the amount of light that comes from a lamp or bulb.

We have created this guide to help you buy the best potentiometer, because you have to pay attention to the most important characteristics of these devices before selecting one.


It is necessary to define the type of device you need, since not all of them work in the same way. Digital potentiometer is used to replace old control devices and is among the most practical.

The digital potentiometer is an electromechanical device, which serves as a knob to regulate the volume of a music player, the brightness of anLCD screen, and even the angle of a stepper motor.

If you’re concerned about how much this device costs, it’s a good idea to mention that it’s an inexpensive device if we take into account its technology and functions.

It is possible to find an encoder with a built-in PCB, which can make the job easier, but it is usually a bit more expensive. It’s possible to classify the potentiometers into two categories, linear and logarithmic.

If the value in ohms varies proportionally to the travel of the cursor when turning the button, it is linear. If the volume of a player increases to 50% of its full capacity when you turn the knob just halfway, it’s a sign that the potentiometer is linear.

When the button is turned up to 75% of its position, the equivalence is asymmetric, so that the volume can increase to 50% when the scrutineer is only 25% of the way.

The intensity is maintained even if you keep turning the potentiometer shaft. In the first few seconds of rotation of the button, the volume of the stereo increases a lot, but then it begins to decrease in the last few seconds.

The potentiometers for Arduino are compatible with printed circuit boards and usually have a linear operation. Since they allow to control different types of digital devices, these devices are very useful for fans of electronics and programming who use the free platform.

It is possible to control the intensity better if you use a multiturn potentiometer, because it allows for a greater range of rotation. This type is less common for users and more frequent within appliances, which is why it is mostly used by specialized technicians to carry out adjustments and repairs.

Technical specifications

If we want to know which one to buy, we have to take into account the specific characteristics of each potentiometer.

If you connect one of these devices to a more demanding system, it is very likely to be damaged, because a potentiometer only works for low power electrical circuits. In this vein, it is known that potentiometers have a maximum resistance value that is expressed in ohms, which we can check on the outside of their structure.

If it says 10K, that means that the resistance can vary from 0 to 10,000 ohms, so you have to choose according to the circuit you are working with. In addition, you should pay attention to the nominal current, which is a measurement of the amount of electricity flowing into a body of water.

It is necessary to take into account the number of high pulse that it offers for each turn of the axis in the so-called rotary encoders. Pressure signal, data signal, clock signal, ground,GND, and voltage are all included in the 5 pins that the most common potentiometers have.


The design of a potentiometer responds to the type of device, but it is worth noting that there is a difference between those for user and technical use.

The former usually have a long and grooved shaft with a metal or plastic knob, which is more comfortable and practical for anyone, in addition, they are resistant and durable.

They can be seen on car radios, as well as on electric guitars and other musical instruments. It is necessary to use a tool to make the necessary adjustments because the potentiometers for technical use don’t have a rotary knob. They are specially designed to be used by trained technical personnel because they are much more fragile.

Frequently asked questions

Q1: How to connect a 3-leg potentiometer?

The connection of a 3-pin potentiometer will depend on the use you are going to give it, but if you want to test the operation of a potentiometer experimentally, you can do it very easily.

The first thing is to name the three legs, in this case, we will call them 1, 2 and 3. In terminal 1 we are going to make a bridge to 2, for this we can use a small cable, adjusting manually or soldering with tin.

2 wires will come out of the potentiometer, one from the junction that we have made between terminals 1 and 2, while the other wire must come out from pin 3. In this way we can make a circuit to regulate the light intensity of a small LED bulb of Christmas.

For this we will need a pair of 1.5 V batteries. On the positive side of the power supply we must connect a cable to one of the ends of the bulb, and at the other end another cable to terminal 3 of the potentiometer.

On the other hand, the wire coming out of the junction between 1 and 2 must be connected to the negative side of the battery. In this way, by turning the potentiometer shaft we will see how the intensity of the light varies.

Q2: How does a potentiometer work?

The potentiometer has a very simple operation. These are 2 terminals joined inside the device by means of a resistive strip, but it also has a third pin in the center that works as an output and varies according to the angle at which we rotate the axis of the device.

If the potentiometer has a value of 10KΩ, turning the shaft to half its capacity, we will have 5KΩ of resistance on each side.

Q3: What is a potentiometer for?

It is a resistor with a special system that allows its value to be varied, therefore, it is possible to control the amount of current that passes through an electronic circuit.

In this way, the potentiometer offers the possibility of changing the intensity level in a lighting system, as well as the volume of sound devices and even the brightness of a screen.

In addition, these types of devices are found inside many of the devices we use today, connected to printed circuits that offer automatic operation, thanks to programming by means of computers.

Q4: How to check a potentiometer?

If you have bought a potentiometer and want to check its operation before installing it, then you will need a digital multimeter.

The first thing you should do is turn the knob on the multimeter to the proper measurement, depending on the capacity of your potentiometer.

In this way, you have to connect the red wire of the potentiometer to terminal 1 and the black wire to terminal 3 of the potentiometer.

The value that appears on the multimeter’s display should match the capacity of the potentiometer. However, it is an approximate measurement, for example, a 10KΩ potentiometer can measure about 9KΩ on the multimeter display, however, this does not mean that it is damaged.

Q5: How to measure a potentiometer?

To measure the variation in the resistance of the potentiometer, you must place the multimeter leads on terminals 1 and 2, to proceed to turn the potentiometer knob.

On the multimeter screen you should see that the value increases as you change the degrees clockwise.

Otherwise, if you put the multimeter leads across terminals 2 and 3, you will see that the resistance decreases as you turn the knob on the potentiometer.
