Email Required, but never shown. Post as a guest Name. Depending on which end you connect the ground and voltage you get a different effect for the same rotation direction. How can I measure what it is outputting before connecting to the LED?

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 datashheet end. Is there anyway I can test? Is it intended for one led, a series of leds? Not made specifically for LEDs.

Home Questions Tags Users Unanswered. If I may, one last question: 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.
The direction bournns the wiper movement is already shown in the graph you have provided, turning bohrns screw clockwise moves the wiper pin 2 towards the end named 3 and turning it counterclockwise moves it towards the end named 1.
It is a simple constant current boost driver. BTW, it is already soldered to a component. You can find burns here: I have a constant current driver for LED with a trimpot to select the output current.
