Did not work :( even when plugging the 9 volt to it. We even checked it with a multi meter and it was giving 4 volts which we concluded should be enough for each motor. This circuit only has two motors soldered to it in to save ourselves a little stress and time. The circuit is soldered to hold 12 motors in total
But we took it to a different outlet to see if that was the issue. But I burnt my finger on the board instead.
