i'm new about arduino and electronics. i want to make a project including sd datalogger. but i had a problem. i'am appreciated if someone show me where i did mistake.
firstly circuit was set as in picture( http://i.hizliresim.com/1kQJDB.jpg ) i am using 8gb micro SDHC card with SD adaptor. I formatted in FAT32. I can play audio files which are in appropriate format and read and the print contents of text files. but when i want to create a new file, strange file is obtained in SD card as in pic ( http://i.hizliresim.com/vL1j6O.jpg ). So I reformat SD card. the code that is used while creating file is as this;
// open a new file and immediately close it: Serial.println("Creating example.txt..."); myFile = SD.open("example.txt", FILE_WRITE); myFile.close();
somewhere I read SDHC card with more tha 2 gb capacity is not supported in aurduino and I bought 2 gb SD micro with SD adaptor. but in this case aurduino does not detect SD card. please someone help me.
