Ardunio Wierdness going on:

i try boil down.  i have identical programs on arduinomega , arduino nove units.  when compile them , try run them on each it's own version of compile, 1 of them worked.  i found if setup on diferent pin, each program work. wierd. also, had needed use pin9 assigned right servo on else , piezo speaker on pin 11 else. now, won't let me simple beep! on diferent pin. thought through software use pin long digital , analog used on same type , defined software. wondering now, whether have blown of ports.

:-?

i know pretty basic question, changing board 'tools > board' menu each time upload 1 of 2 boards?

you may doing that, since "... on each it's own version of compile, ..." need every time upload other board, , results describe if forgot each time.
