cut a pvc tube so that it take the size of the shoebox in length. take the HC-SR04 sensor and put it at the end of the tube and fix it with tapes so that it aim into the tube 

make an incision next to the tube on the shoebox so that a piece of wood can fit. make it stay in place by piercing a hole in the piece of wood and take a longue cylinder that goes through the hole and s-the box so that it is fixed

put the pressure button under the lever so that when you pull the lever it push the pressure button and you are done for the first box 

take the second shoebox and make two circle incision so that the joystick can be put through and put tapes so that they don't move and only the tip of it goes out. take a flat and round cardboard piece and make an incision so that in can be placed on the tip of the joystick and put tape so that in is fixed together. then take aluminium foil that you shape in a rectangle form and fix it with tape on top of the tip and you're done 

connect the pressure button and the two joystick to the usb card and the sensor to the Arduino micro and change the input with joykeymapper and change them in the game and you can play
