I am designing a large model railway in a barn measuring 30 feet by 30 feet. It will encompass two large terminal stations, two large through stations and several intermediate stations.
I intend to use multiple Mega controllers at each terminus as I anticipate some 50+ track locations and 40+ signals in each terminus, its approach and yard.
After I have programmed a controller, I want to move it to its permanent location and then program another one, and so on.
If I bring a controller back in to the computer from the layout, I will want the IDE to identify the board and show its configuration and settings. If there is a way to set something that would, for example, define one board as number 1, then define number 2, and so on, that is what I am asking about.
Is there a way to have boards defined or setup this way? I'm suspecting there must be, but just can't find anything explaining how this is done without possibly damaging the board.
As an FYI, I am new to Arduino so will be slowly building up over the coming year or so. Plus, I don't see any need for my multiple Megas to be wired together, I just anticipate that I will need 5 or 6 of them to run the railway and power the lighting on my control panels.
Many thanks in advance and apologies if this has already been answered somewhere.
