I am working on a project where i want use the Arduino Wifi shield and the Sparkfun El Escudo Dos: https://www.sparkfun.com/products/10878. Is it possible to use both shields at the same time. What would i need to do in order for this to work. I do not know a lot about this stuff and any help that i can get on this would be greatly appreciated.
Sparkfun El Escudo DOS uses D2 to D9 Output pins.
Wifi Shield needs SPI pins 11, 12, and 13 on the Uno and Pin 10 to select WiFi or SD card.
So you can use bouth cards.
