Replace SD Card Reader by modified SD Adapter

It is also possible to use an SD Card Adapter. You have only add pins to the adapter an then you can use it on the breadboard. If you use a modified SD Adapter a supply voltage of 3.3V is needed instead the 5V used by the SD Card Reader in the circuit diagram!
