Hi there, I'm wondering if I can use a 5k ohm digital pot where a 4k7 ohm analog pot used to be?
There is .3k ohms of difference of resistance, so would that mean that I would have to crop that off in my arduino code maybe using the map function perhaps?
This is where I'm wanting to buy the 5k ohm digital potentiometers from.

I'm wanting to digitally control a 24vdc speed controller. Unfortunately for me the speed controller uses a 4k7 ohm analog potentiometer, and I want to replace that and use a digital potentiometer and control the speed using an arduino. Buuutttt, the element14 website where I get my electronic components from looks like they only sell 5k digital pots...
Thanks very much in advance!!
