I am using this micro-sd card reader, and my wiring configuration is as follows (double and triple checked):
3.3v goes to 3.3v on the Arduino UNO
GND goes to Ground on Arduino UNO
D0 goes to pin 12 on Arduino UNO
D1 goes to pin 11 on Arduino UNO
CLK goes to pin 13 on Arduino UNO
D3 goes to pin 4 on Arduino UNO
When I run the 'basic' example from the TMRpcm library, everything compiles and uploads properly with no warnings. Looking at the Serial Monitor, I get "SD Fail", which, according to the comments, means that the SD card failed to initialize. The card is present, and works in my computer. Do I have something wired wrong, or is there another issue?
I have tried using a different pin for D3, and changed the code as needed. Still no luck.
