Light sensor :

At first, we wanted to be able to take the sword fully out of the rock. But one problem persisted: we had the light sensor at the top of the sword that needed cables to be able to work properly. We tried to fix cables on the sword and to put 3 distinct parts of aluminium in a receptacle inside of the box. However, this system is not perfect and fails often. As we did not have time to work more on it, we came up with one solution to improve the project in the future. We could use magnet instead of aluminium so that the cables would be attracted to the magnet and therefore connect properly to the rest of the system.
