Check inside please:

For Arduino,

it tookd me around 30-60 minuts to download the Arduino software and add new libraries.

For each program, it  probably took me around 30 minutes.

For Respberry Pi 4,

it took me at least two more days to download the operating system, get used to the new operating system and make it work.

For the hardware of connecting 9 matrix boards, it took me around 3-4 days.
