I am trying to make a kind of datalogger but at first instance I just want to try to write some info (the status of a variable) to an SD card. So I bought a 'Deek Robot Data Logging Shield V1.0' for my arduino uno. On this extension a lot of holes are foreseen to solder, I suppose to add directly the sensors but since I'm not using any sensors I just tried to attach the board to my arduino uno by plugging it in from the top. I didn't do any additional wiring and uploaded the SD card datalogger example but it always gives the error 'Card failed or not present' The card(microSD+adapter) is present though and it works on my computer. I also checked the file system (FAT32)
Could anyone give me some backup because I don't know exactly what could go wrong or what I could be missing (newbie)
Any help is appreciated!
