Hi!
I am battling to get the Sparkfun mp3 player shield to work with my Uno. I want to trigger it with a Pir sensor and play random mp3s from the sd card.
But I can not get past this error:
Free RAM = 917 Should be a base line of 1017, on ATmega328 when using INTx
Can't access SD card. Do not reformat.
No card, wrong chip select pin, or SPI problem?
SD errorCode: 0X20,0XFF
F_CPU = 16000000
I am following this tutorial: MP3 Player Shield Hookup Guide V15 - SparkFun Learn
Please help, anything that can get me further on is very much appreciated!
All good

Please post schematics. Several possible reasons for failure there.
The memory issue is bad. Hopefully another helper can handle that.
Sorry but that is not schematics at all. Pictures are not at all useful to track wiring faults, unless You want to wait a very long time for a helper being a retired detective taking on Your case.
Try pen and paper. Don't go for Fritzing style pictures.
SOLVED:
Sorry for bothering. But I solved it by changing sd card and soldiering it properly, so the pins goes down enough to the Arduino. Also by connecting the Arduino with a power source makes the quality and the speed correct.
