First buy the pico and a bread board connect them together.

Next connect the joystick and button to the pico

Plug the pico into the computer while holding the button on the pico. Then copy the correct UF2 file into the pico storage.

Download the Mu code Editor and select the mode RP2040

Copy and paste the code in hit run and make sure it works

To assemble the box cut it out of 3mm play wood using a laser CNC cutting machine.

I recommend using clamps and using a mallet to assemble the box. 

once the box is assembled you will need to dremel a small hole in the bottom wherever you wish to put the breadboard. 

 Continue to print the other parts like the lid and the spacer.

Make sure all of your code is working before assembling the parts and gluing them down.
