Reading and Writing Files from an SD Card with an Arduino

In some Arduino applications, it is advantageous to be able to store and retrieve information locally. You can do this with a Secure Digital, or SD, card. An SD card is a non-volatile memory card used extensively in portable devices, such as mobile phones, digital cameras, GPS navigation devices, handheld consoles, and tablet computers. Another type of SD Card is the Micro SD card. Measuring only 15 mm x 11 mm x 1 mm, it is the smallest memory card available. It is about one-quarter the size of a normal-sized SD card, or about the size of a fingernail.
