Hi everyone!
I'm currently working on my first project and even though i surfed through many schematics of wirings i still don't understand how exactly does it work, especially led implementation :( Could anyone explain it to me?
Also i was about to use io from mbp library and ran in the same problem... How does led resistor should be mounted? Should L pad and led cathode be traced and anode conected to ground? Thanks in advance!
p.s sorry for any spelling mistakes i might have made....

It doesn't matter which leg of the LED the current limiting resistor (CLR) goes to. The short leg (negative / cathode) of the LED always goes to ground and the long leg (positive / anode) always goes to you positive power supply line.
