resistors – trimpot adjustment – Electrical Engineering Stack Exchange

Depending on the way the trimmer is wired the rotation direction can have a specific meaning. Post as a guest Name. You can find it here: BTW, it is already soldered to a component.

I don’t want to kill the LED in case it is too high? By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Datasheeg. Depending on which end you connect the ground and voltage you get a bohrns effect for the same rotation direction.

If you connect ground to one end and a voltage to the other end then the wiper becomes the middle point of a voltage divider and the output changes based on the actual position. I’ve got a trimpot like this one: How can I measure what it is outputting before connecting to the LED?

The direction of the wiper movement is already shown in the graph you have provided, turning the screw clockwise moves the wiper pin 2 towards the end named 3 and turning it counterclockwise moves it towards the end named 1.

You can’t define an increment or decrement of the resistance, all that you do by turning the trimmer screw is move the wiper toward one or the other end.

I have a constant current driver for LED with a trimpot to select the output current. So, it is “neutral” so to speak? If I may, one last question: Is it intended for one led, a series of leds?
