As you seem to need lots of I/O pins a Mega would seem the obvious choice. But you need to count up all the pins you require and check with the specs for the Mega.It is possible to use I/O extenders to create extra I/O ports for an Uno - but I think that would just make the project unnecessarily complicated for a beginner.

with mega arduino it would be difficult ?
No where is each cable or that programming has .
Mega you advise me ?
