Noob here
Have a UNO that I am trying to get the sparkfun Micro OLED Breakout set up for SPI (if I read things correctly) and a generic Micro SD Card Reader (via SPI?) to both work. :?:
Both need Pins 10, 11, and 13 for CS, MOSI, and SCK.
Micro OLED also uses 2 additional pins besides 3.3V power and ground (8 & 9 in my setup)
Micro SD uses pin 12 (MISO) in addition to 5v power and ground

How do I set up so I can use both OLED and Mirco SD on the same UNO?
I want to display information and write it to a SD card.

Thank you
