I have an Wireless LED costume project using xbees and I wanted to add an SD card, but from what I'm reading, the SD card uses the same SPI pins (11 and 13) that my LED sketch uses. I'm using the (old) bliptronics LPD6803 library to control the leds. My goal is to add more storage so I can have more light patterns. What can I do? My hardware is xbee with sparkfun's regulated breakout to an Arduino pro mini via FTDI - LEDS connected to pins 11, 13, and ground.

SPI is a bus that supports multiple devices. They share the MOSI, MISO and SCK lines, but each device has it's own SS line. The SS, (Slave Select), lines select which device is active at any given time.
Thanks for your help. I will do some research on that.
