SD Card / FAT32 Interfacing with ATmega8

CC Dharmani shows how to easy connect a SD card to an ATMega 8 microcontroller.

In this project the 1GB microSD card is used. The microcontroller is AVR ATmega8, running at 1Mhz internal clock. MAX232 is used to interface the circuit with PC for monitoring the data. All the chips (ATMega8, microSD and max232) are powered with 3.3V.
