# Arena - Hardware mapping

If your experiment is set to use of Trial control hardware, the Hardware mapping section at the bottom of the Arena Settings pane is available. Click the Arena-hardware mapping button to assign hardware devices to each of your arenas.

If your experiment consists of only one arena, the hardware is automatically assigned to this arena, so you do not have to take further actions.

If you have more than one arena, assign the hardware to the arenas manually.
