- SD card test
-
- This example shows how use the utility libraries on which the'
- SD library is based in order to get info about your SD card.
- Very useful for testing a card when you're not sure whether its working or not.
-
- The circuit:
- SD card attached to SPI bus as follows:
- ** MOSI - pin 11 on Arduino Uno/Duemilanove/Diecimila
- ** MISO - pin 12 on Arduino Uno/Duemilanove/Diecimila
- ** CLK - pin 13 on Arduino Uno/Duemilanove/Diecimila
- ** CS - depends on your SD card shield or module.
- Pin 4 used here for consistency with other Arduino examples
