Forgot to mention:

this looks like a candidate for an "Arduino" package which contains all the
renames, so you can "with Arduino" and write
   Arduino.Led := On;
or, if you want to drive the port directly, simply read the package instead of
rummaging through data sheets and schematics.

Led types should be enumerations, or renamed subtypes of boolean, (On,Off) or
(Off,On) according to the way they are connected, rather than (True,False).
