SD card interfacing with microcontroller

Here we will program to log the temperature reading from a LM35 sensor to a text file periodically. A 32GB SDSC card from Transcend is used in this particular project, but the code will work with most of the SD cards. The SD card is formatted with FAT32. The ultimate aim of this project is to create a file in the FAT32 file system of the SD card.
