Yes, you probably want to flip the whole experimental setup around
and attach everything that was on one electrode to the other and vice versa.

So, if you cannot see how to do that via using different pins of the microcontroller,
you could add an analog switch IC to act like a patch panel.

Or, get big or small medieval style DC relays chunking or clicking to do the swap around.
