digital pin used for more then one thing?

i need to set up two indivisual external items one is a wireless ps2 controller the other is a sd shield they both take up some of the same pins will it work or is it possible for it to work. thanks:)

Typically no that will not work. That is called a pin conflict and usually can only be fixed by modifiying on of the devices so they utilize different pins. However sometimes there is a way in software to ‘disable’ one device by some means so that the pin can still be used by the other device. Maybe if you can provide links to the two device’s schematic drawings and tell us which pin is in conflict, someone here maybe able to provide you will a software ‘work around’.
