Configuring 3 Slaves

Configuring 3 Slaves
« on: April 23, 2014, 02:44:12 AM »
Can anybody tell me how to configure an SD card, wifi-shield, and the serial monitor to all work simultaneously on an Arduino Mega 2560?

P.S.: I'm aware that this site is for tiny circuits; however, I read a similar thread (http://forum.tiny-circuits.com/index.php?topic=212.0) and considered my question to be relevant.

Any help will be well-appreciated.
