Excellent craftsmanship, smooth movement, reliable and stable performance, insulated and dustproof interface, high protection level.

The potentiometer has three outputs. With connection to only two of them, it can be used as a rheostat and adjust the current strength, however, all three outputs are usually used and the variable resistor serves as a potentiometer, i.e. controls the voltage value.


When connecting the output of the potentiometer to the analog input of the Arduino, it will be possible to read this value and set it to some other value (for example, change the brightness of the LEDs or the volume of the sound).
