Motor Speed Control via Single Poteniometer?

[RossWaddell]

Is it an encoder like this that is what sits behind modern stereo volume controls?

[mister_e]

Most new sound systems indeed use rotary encoder, mechanical or optical, like the one you linked to. Some also have push switch on their shaft. You see them on car radio, MIDI controllers, mixing consoles, etc etc. Really handy piece of hardware, specially for surfing in a menu...

[RossWaddell]

Based on another example I've order this encoder. As far as wiring up to a PIC goes, does this schematic look right?

[aratti]

Yes, the wiring is correct. You could use the code snip given @ http://www.picbasic.co.uk/forum/showthread.php?t=12911
to start counting your encoder pulses.
