Hello,
I gave a potentiometer 1kOm, so it goes from 0 to 1 kOhms. I want to use this potentiometer as speed sensor for my application. The problem is that i want to use it with velleman K8055 board. At first i thought that i just lead 5V though the potentiometer, but there is way too less resistance.
Could any1 help me to do this?
principle is like this:

potentiometer will be moved by my application. Currently 0 to 1kOhm resistor makes absolutely no difference at all, it moves by 2 bards of 255..
I think i need a voltage divider circuit or something
