You should now have a list that looks like this, showing all three of the
boards we're going to use in this project. Pay attention to the order of the
boards in the list! They must match the order of the boards in hardware! If
the order of your boards differs from that in the image above, you can use
the up and down carets (in the board name bar) to change the order of the
boards.
Now you'll need to add actions to each board, to tell the Spectacle system
what sort of behavior you want. Click on the clapboard icon (highlighted
above) for the Button Board to pull up the "Edit actions" frame.
