Ok... i should really know this.... normally when i see a pot used, it's used like this: Where from the top to the bottom it is the full max value of the pot (i.e. for a 5k pot, it's 5k), and on the right (with the arrow) is the variable lead of the pot.
Now.... on this pic.... I don't see how i'm supposed to wire the pot up. it just shows two sides... do i just connect to one side, and the variable point, and leave the other side open? I guess i'm just not understanding the schematic. It's direct off of the LM-317 datasheet at http://www.national.com/ds/LM/LM117.pdf if that helps you explain any.
Thanks in advance
