Frequently asked questions
How do I wire it to an Arduino analog input?
Connect one outer pin to 5V, the other outer pin to GND, and the centre (wiper) pin to an analog input such as A0. Turning the shaft changes the voltage on the wiper.
Can it be used in high-power or mains circuits?
No. It is a low-power control component meant for signal-level adjustment. Check the manufacturer datasheet for its power rating before using it in any power path.
