PaulS:
Could be either one. Depends on whether you want to read a whole record, then parse it, and convert each token to an int, or whether you want to read and parse in one step, as you are doing now.
Probably the first method, read till I get a new line, then parse the whole thing. Unless you can think of a reason why I should be doing it one at a time. In the end, I'd like to just pass all the arguments on to the servo function as one piece (at least, I think I can.) So something like myServos(arg1, arg2, arg3, arg4). The pause argument is being used by the main loop itself, not the servo function.
