Not a rockstar. Not a ninja. Just professionally awesome.


  • Is there any other common misstep to check for? I’m using an Arduino Uno, the board has soldered headers, I’ve tried reformatting the cards and different versions of MP3 files but I consistently get the same error message:

    “Can’t access SD card. Do not reformat. No card, wrong chip select pin, or SPI problem? SD errorCode: 0X1, 0X0”

No public wish lists :(
