Frequently asked questions
How do I wire a 3-pin trimmer as a voltage divider?
Connect the two outer pins to the supply voltage and ground, and take the output from the center wiper pin. Turning the screw changes the output voltage between the two extremes.
Can I use it as a variable resistor with two terminals?
Yes. Connect the center wiper pin to one outer pin, and use the two remaining connections as the variable resistance. This is useful for setting a current or bias value.
