arduino microsd shield
The communication between the microcontroller and the SD card uses SPI, which takes place on digital pins 11, 12, and 13 (on most Arduino boards) or 50, 51, and 52 (Arduino Mega). Additionally, another pin must be used to select the SD card. This can be the hardware SS pin - pin 10 (on most Arduino boards) or pin 53 (on the Mega) - or another pin specified in the call to SD.begin(). Note that even if you don't use the hardware SS pin, it must be left as an output or the SD library won't work. just visit : http://www.hobbytronics.co.uk/arduino/arduino-shields/arduino-microsd-shield Documents: Schematic Eagle Files SD Library (FAT16 and FAT32) Example Sketch GitHub (Design Files & Example Code) need SD Library ???
