+Finalized the physical enclosure by adding the side walls and the top playing surface complete with the chess sticker. Installed the initial piece detection matrix, wiring and validating the first two rows of reed switches through a multiplexer. Furthermore, integrated the transistor-controlled electromagnet and successfully executed the first physical test to move a piece.

+Connect all reed switches to the MUXs and the STM32 Nucleo. Reprint the 3D chess pieces to make them lighter and use only one magnet. Write the software to read all reed switches and mirror all the moves that the white player makes.

 ## Hardware
 
 The hardware setup includes an STM32 microcontroller, 64 magnetic Reed sensors for piece detection, two Nema 17 stepper motors for the CoreXY movement and a 12V electromagnet to physically drag the pieces.
