Potentiometers

I'm currently working on a project where I use a potentiometer as a dial to turn on different sets of LEDs. My problem is i don't know which potentiometer to get. Would the ohm rating of a potentiometer matter at all when using it like this? Are there other factors to take into consideration? The project book i have doesn't really go far in depth about the hardware side of things.

10k lineair is a common value. It sometimes has 10kB printed on the case. Leo..

I've never seen that.

I have some 10k pots like below and they seem to be a good general match for the arduino.

AWOL:
I’ve never seen that.

Please correct me if I’m wrong.
AFAIK A stands for log (Audio taper), B for lineair, and C for reverse log.
10kB or B10k is 10k lineair.

Hi.

You are correct, old code vs new code.

Taper Old Code New Code Alternate Linear A B LIN Log (Audio) C A LOG Antilog F N/A N/A
