I set up the arduino this way to connect a micro SD card to it for extra memory.

Step one is to get regulated 3.3V to the SD card. I used an LM317T and some resistors to take the 5V from the arduino and turn it into 3.3V.

I purchased the micro SD card breakout board from SparkFun electronics.

Step two will be to write the firmware. This will be discussed in my next installment.
