This is a tutorial for an escape room puzzle in which players must rotate paintings on a wall to depict the correct subjects. When all the images are rotated to the correct orientation (as determined by a magnet embedded in the side edge of the frame, detected by a magnetic sensor in the back board), an Arduino activates a relay to release a maglock.
