Reconcile Analog

it's known problem analog ports not return proper pin names when this:

servopin = a0;

serial.println (servopin);

this such basic problem can't believe @ level (almost no programming experience) dealing it, here am.

if above on uno, returns 14. a0-a5 (6 analog ports) 14,15,16,17,18,19.
if on mega, returns 54 start through 69 a0-a15.

this makes rather difficult tell user port supposed using analog input:

serial.print ("this controlled potentiometer @ pin ");

so, here solution. problem is, not programmer hoping can streamline code bit. following 2 pin solutions!!! since run mega, need expanded 13!! using library functions this?

code: [select]
