so the problem is i cant connect both of them to a single arduino uno because they need the same pins 11/12/13
Does your city have buses that have just one seat each?
Pins 11, 12, and 13 are the SPI pins. Any number of devices can be connected to the bus, as long as each has a separate slave select pin.
the problem is i don't know how to do that and how to program both of the two arduinos
The problem is that you don't understand that two SPI devices CAN be connected to one Arduino, and that you haven't defined any requirements. You can't even begin trying to write code without requirements, nor can you expect anyone else to write code for you.
