linear rotary pot

iv always been under the impression that a linear pot was a fader?? so im sorry bout this but… this has put me back to square one!

could anyone tell me this is a mistake or…

thanks =[

Both rotary potentiometers and faders can be linear or logarithmic. Linear pots give you proportional values (the distance between the values stays the same). With a logarithmic pot you get values of a logarithmic function (the distance between the values varies).
This should make it clear (I hope): Potentiometer - Wikipedia

But the usage of the term “linear” seems to be a little inconsistent as some faders on one of the pictures are titled as “Linear potentiometers”. This can be a little confusing I guess :wink:

I believe you are confusing linear pots with slide pots/faders :slight_smile:

thanks =] appreciated

gonna have a quick read up in that page now

ok so the plan essentially is to turn…a gamepad into a basic controller. ive bought 12 arcade buttons, and (from what i understand) i can use 2 linear rotary pots, and 2 linear faders? that would get the job done?

but the wiki also says about the log, so uh… wow. is log a better choice?

thanks again:open_mouth:

tbh, I don’t no much about gamepad mods. I’d recomment browsing through the Threads of Interest there are some gamepad based build logs you should check out.

I would go with the linear pots as they give you nice proportional values. Logaritmic pots have their uses but it would give me some kind of a weird feeling to have unproportional values because if your physical knob is at say 12 o’clock your corresponding knob in the software of your choice won’t be at 12 o’clock/50%.

ah that makes more sense now! ok thanks =] il eventually put out a build log when i get the casing sorted ;]

Cool. Always looking forward to good build logs :slight_smile:
